if you haven't started collecting teeth, do it. You won't need more than a couple your first year, but you will need good specimens of pretty much all teeth for Endo classes your second year. A boatload of third molars will only serve you so much.
As far as living arrangements, I have a couple of classmates (females) who live in the dorms and have done so since the beginning. There are more of them who started out that way and moved out. There are TONS of apartments and houses around the school and within walking distance. Whatever size of domicile you are looking for, it can be found within reasonable distance from campus.
My recommendation to you would be to brush up on your biochem, especially, and it couldn't hurt to do some anatomy and physio as well. Otherwise, just make sure all your paperwork and financial aid and whatnot is taken care of and just chill as much as you can before school starts.
Thanks!
