Hi G and J,
On the matter of teaching pastors versus preaching pastors, any difference would simply be a matter of the meaning a given church imputes to these respective terms. There is no reference to such offices in the New Testament. That doesn't mean that it is necessary to organize the leadership exactly as the New Testament churches were organized—though I would generally think that to be preferable.
The first century churches did not have a position called "pastor." The Greek word "pastor" (poimen) is the ordinary word for "shepherd. It is used, most commonly in the New Testament for ordinary sheep-herders. Secondarily, it is used of Christ, the Good Shepherd. Only once in the New Testament does it refer to church leaders, and only in the plural (Eph.4:11).
The shepherding role in each church was carried on by a group of men referred to as elders (Gr. "presbuteroi") or overseers (Gr. "episkopoi"—traditionally, and unfortunately, rendered, in the KJV, as "bishops").
These terms are used interchangably in Scripture (compare Acts 20:17 with v.28/ Titus 1:5 with v.7/ 1 Peter 5:1 with v.2). Each congregation had a group of "elder/overseers" (Acts 14:23; 20:17/ Titus 1:5/Phil.1:1/ James 5:14).
This last reference is Paul's greeting to the officers of the Philippian church. It is significant that he does not greet "the pastor." This is because the "elders/overseers" were the "pastors/shepherds" of the congregation. We never read in Scripture of a church having an individual leader, called "the pastor." The tradition of a congregation having a single "overseer" began early in post-apostolic times, and is first mentioned in the letters of Ignatius (d.115 AD).
Whether the development of one primary leader per congregation may or may not have been a positive development, the factn remains that this arrangement was unknown in New Testament times, meaning there is no teaching in the Bible about this role.
"Preaching" and "teaching" differ from one another in Scripture, primarily, in the composition of the audience. The term "preaching" is used in the New Testament almost exclusively in connection with "preaching the gospel" to unbelievers—that is, evangelism (e.g., Acts 8:12, 25, 40; 14:21; 16:10; 18:5, etc.). In biblical times, this was usually not an activity conducted in the church services, but among unbelievers. The church gatherings were for the purpose of actual believers coming together to fellowship, worship and receive teaching (Acts 2:41-42/ 1 Cor.14:6, 19, 26). For this reason, the qualifications for elder/overseers included the ability to teach, but not necessarily to preach (1 Tim.3:1-7 / Titus 1:5-9).
Thus the "pastors" (elder/overseers) are distinguished from "evangelists" in Eph.45:11—the former being the leaders of the congregation, and the latter conducting their ministry among the unbelievers outside the church. Jesus commanded that the gospel be preached throughout the world, to "every creature" (Mark 16:15), but that the converts that are made should be "taught" to observe "all things whatsoever I have commend you" (Matt.28:19-20).
Modern churches, unlike the early church, have a lot of attendees who are not really converted, so preaching is the primary pulpit activity. Unfortunately, this limits the opportunities for the true Christians to be taught and discipled. The gatherings intended for their edification and instruction are often focused on the lowest common spiritual denominator—which usually means the unconverted visitor, whom the churches are careful to avoid offending with anything like straightforward and in-depth teaching. I believe that this has kept the churches weak and ineffective in making dynamic disciples. A new church plant has got to decide whether it will follow this pattern, or will try to recover the biblical norms. This decision will determine whether they hire a teaching pastor or a preaching pastor—or, if both, which will be seen as the main speaker at the services.
On the subject of female pastors, I would direct you to my comments to another person (a woman in seminary) who asked about this matter. It is found at our "Bible Forum," accessible from my website. The link to the relevant discussion is here:
As for the advisability of women being selected as pastors (elder/overseers), Paul advised against it in 1 Timothy 2:12ff. It is significant that this is given in the immediate context of his giving a list of qualifications for overseers, who (he said) must be husbands (3:2).
There are some who suggest that this gender requirement was based on either 1) Paul's residual prejudices from his Pharisaic past, 2) Paul's wish to accommodate the chauvinistic sensibilities of his culture, 3) Paul's concern that women, in his day, were not as educated as were men, and could not be trusted to teach, or 4) Paul's concern for a particular group of heretical female teachers in Ephesus, whom he wished to debar from pulpit ministry. These suggestions are made in order to argue for the suspension of this restriction in the modern world, because of the changed culture and circumstances.
The only problem with any of these suggestions is that Paul actually gives his rationale in the very passage itself, and it is not similar to any of the suggestions! Paul says that the propriety of the role of overseer being reserved for husbands rests upon the way in which and purpose for which God created the genders (1 Tim.2:13), and also their respective roles in the fall of mankind (1 Tim.2:14).
Obviously, modern people, conditioned by modern culture, can opt to disagree with Paul's reasoning and his conclusions—but they cannot honestly claim that Paul viewed his instructions as limited to a certain age or culture, since the creation and fall are unchanging historical facts, the implications of which have not changed from Paul's day to ours. Thus it is not Paul who is "culure-bound" in his instructions, but those who disagree with him in a modern feminist age. It is their cultural milieu that is dictating their opinions.
You can expect to hear some cat-calls against you any time you champion the positions espoused by the Apostle on this unpopular topic in this modern age. However, when Paul was writing elsewhere on the conduct of women in the churches, he anticipated the objections, and attached this rebuke to dissenters:
"If any thinks himself to be a prophet or spiritual, let him acknowledge that the things which I write to you are the commandments of the Lord" (1 Cor.14:37).
If I were on a committee considering going against Paul's (the Lord's) commandments, I would seriously reconsider. Even if some people in the decision-making position do not feel compelled to submit to the Scriptures in this matter, they should recognize that there are still many evangelicals who believe that the Scriptures are the Word of God and that the Church ought to be faithful to what God has said. No amount of argument will convince some of these people (since there are no biblical arguments to be made against Paul's position), and the choice of a female pastor will certainly alienate these people unnecessarily, where the choice of a man fitting Paul's qualifications for an overseer would not alienate them. It is true that a church with a woman as pastor may still attract enough congregants to keep the bills paid, but the quality of those who are alienated (that is, people committed to and knowledgable in the Word of God) would be just the type that a church ought most to covet in their membership.
I have gone on long on this subject, but am capable of going longer. In fact, I have addressed these issues in greater detail in the following lectures in the "Some Assembly Required" series, which can be heard at my website:

I hope I may have been of help to you (and not get you into trouble!). God bless you!
