Ok good choices. I always recommend that people not pick pre-med or pre-vet as a major, because if you graduate and change your mind or (God forbid) aren't accepted anywhere, you couldn't get a job doing anything. But anything in biology or chemistry is perfect. When you start let me know what books your classes require, for the classes like chemistry, calc, and physics I am totally willing to just send you what I have if they're the same books.
