ReNae,
You might want to take a look at the following topics and see if some of your questions are addressed there and then post about anything where you still need answers:
Must Haves for the Studio
Book Advice for the Beginner
Recommended Books for the Portrait Painter
Most of the books mentioned are linked to Amazon where you can read more about them and order if you so choose.

Good luck!
