I don't want to be the pessimist here, but those scores are just barely enough to apply. You need to 700+ GRE scores and a minimum of 3.7. On a positive note though, they only typically look at your last two years of grades, so if those are higher, you're in good shape.
Of course, you'll need to show that you have research experience and perhaps even clinical experience.
Lastly, you'll need to start contacting your potential supervisors early... start now if you're looking to apply for admission for the Sept 2013 year.
Good luck!
