I just went through the phd application process this year, for biomedical sciences, and was accepted at several schools. The catch is...I have the same GPA as you but I have been working for a few years after college. The research experience and subsequent letters from my mentors are definitely what got me into graduate school. If you are considering working before applying to graduate school, there are other options other than academic technician jobs. I have done preclinical research for biotech companies. I know there are a bunch of private companies in the bay area, many of them spin-offs of academic research.
As far as the GRE, I had a good score and also took the subject exam, studying for each about a month or so. I applied to a wide range of schools, had several interviews and will be attending a top 25 school with a good reputation. Defintely apply to a broader range of schools, ones that you feel are a good fit for your research interests. Good luck with everything!
