I am about to send in my application for spring term too. I called them yesterday and here's what they told me. They look at 2 GPA's, pre req and last 45. The 3rd major component to determine who gets invited for an interview is the GRE. They guy said to be competitive for this term you should be around a 3.4 gpa with a gre score of about 297. Also since I am currently a paid employee at a pt clinic, I asked if i should wait another month for accumulate more hours, and he said that there is no "extra credit" for going over their required 80 hours, and to send in the application asap (but obviously more hours will help your in the interview). I hope this helps!
