How many classes are you taking this upcoming semester and in the summer semester? If I were you, I would CRAM as many in as possible. Consider retaking at least a few of whatever pre reqs are bringing you down to a 3.0 as well as whatever other classes you can sign up for. The 3.2 cum isn't too bad but the pre req GPA will hurt you. (Look at online classes, something you really like to boost your cum GPA and then tackle lowest grade first on retaking pre req classes)
My other recommendation is to wait until your summer class grades are officially in before submitting to PTCAS. You may have to wait a bit longer than you would like but it will be well worth it to have more of a grade boost (I had to wait until the last week of August to get final summer grades....but that still put me quite a bit ahead of the October deadline. Many people miss understand this part....yes, you "could" submit whenever you want, but after PTCAS does it's calculations you will not be able to update grades again until December. Many schools will make a decision on you before you can update grades in December)
How is your GPA for your last 60 units? If it is significantly better, you could target those schools.
