For US History what is a good starting point?

I'd suggest you give the history department at UNCW a call. Ask to make an appointment with whomever is in charge of the teaching of history program. When you have your meeting, have a list of questions, including:

What should I be doing now to prepare for the transfer to the university?

What should I be reading or learning to better prepare myself for teacher education?

Are there books or articles that you would recommend that are specific to the teaching of history?

Does (your state) recognize different types of history (US, European, modern, ancient, etc.) for licensure? If so, are there more jobs available for one of these fields?

What is the university's track record with respect to student teaching and job placement?

Ask if there are any 3rd- or 4th-year students you can speak/email with to learn more about the program.

And probably lots more.

Most two-year colleges offer advice to transfer students. This usually involves working to maximize credits that transfer and to ensure that all of the student's paperwork is correct, etc. I'd definitely try to avail myself of that service. A good friend of mine performs this service for the City Colleges of Chicago. She is great at her job and works very hard to be sure students have the best chances of success at the 4-year school. I'd bet whomever does this job at your school is equally helpful.

To editorialize a bit, good on you for starting at a two-year school. There are of course a multitude of reasons why you made that choice -- and none of them are any of my business -- but I've found that the undergraduates I teach that come from a two-year school are far more committed to their education. Good luck.
