Wow the post bacc only brought you up to a 2.99? You must have had a ton of undergrad credits...
So here is the best that I can suggest. Apply like right now, like as soon as physically possible. There was one possible flaw. There seems to be not much that you can do about the gpa. You did a post-bacc and obviously worked hard. I imagine that they will see that. GPA repair seems to not be a very good option. Definitely apply to more schools. Maybe NYIT, VCOM, CUSOM, MUCOM (technically not the east coast but not terribly far from you), try again at PCOM, and Rowan, and then maybe a few other schools that you could see yourself at.
Dont worry about the wording on your ECs, they wont remember any of it. Maybe just change a little for anything that you have continued. Like if there was any further growth or advancement in those positions.
Apart from that the only thing you could do is to kill the MCAT. You get a super solid score on that and it could definitely help carry you through the cycle, especially at some of the stat heavy schools (like Rowan). A good post bacc combined with a good MCAT makes you pretty darn competitive. But again, the whole MCAT thing is up for you to decide. Either way you will waste time and money. You could apply to more schools (like 12+), fill out more secondaries, go on more interviews (so all of that is time and money), or you could take the MCAT, take more practice tests, etc (time and money). I think you could be successful so long as you are strategic. But even if you bust out a 29 on your MCAT, I personally would still apply to more schools, just in case.
