I have very similar stats as you - I have a 3.3 overall and about a 2.9 prereq, I believe - My overall GRE score is the same as yours - I'm currently taking a class for the GRE and am retaking it in a few weeks
This is my second time applying to PT schools; however, last year I applied really late (submitted PTCAS in Jan) and to out-of-state schools that only took 3-4 out of state students.
What I do have going for me is I went to a good, well-known, school and I have around 300 volunteer hours (geriatrics, pediatrics, orthopedics, lymphedema/wound care). I'm also currently interviewing for PT/rehab aide positions.
When I applied last year I had about 100 hours and my overall GPA was a 3.2. I've since completed a 240 hour internship.
Make sure you apply early. I'm hoping rolling admissions will help me this time around, and apply to schools that are familiar with your undergraduate program.
Since this is my second time applying, I'm also applying to accelerated nursing programs as backups (although I don't think they are easy to get into either) - if you really don't want to take a year off, maybe consider other types of programs as a second option. I've talked to some students who have said taking a year off ended up being the best thing they ever did; although so far I can't say the same, I'm hoping I eventually agree.
I'm not trying to discourage you, just trying to give some tips - basically apply early!
