Pre-med site is in the works, but for now, here are some excellent resources online:

Association of American Medical Colleges - Student page This is a professional site from AAMC that contains information about considering a professional career, tips on applying, financial planning, and anything else you could want.
The Premedical and Medical School Admissions Guide This guide was written by a medical student for pre-meds. The Guide is intended to give American premed students advice for the premed track through the end of the actual application process.

Check out the Links page as well for links to more professional sites and required testing.
