I thought you were getting solid advice in your other thread.
1)Start taking ugrad science classes. Get as many (ie all) A's as possible to boost that GPA
2)Kill the MCAT (34+ given your GPA)
3)Build ECs (clinical volunteering, teaching/tutoring, research, shadowing, leadership)
4)Collect LORs (science profs, clinical supervisors, etc)
But #1 is the linchpin for you. You don't need a formal post-bac though some like the bells & whistles (ie committee letters, application advice, referrals to ECs). I did an informal post-bac to boost my GPA.
I'll just reiterate, steel and commit yourself to getting A's. With your prior transcript every academic misstep will delay your GPA reclamation project by years. Clear your plate of distractions and be judicious with your EC load and courseload. Take on as much as you can but only enough that allows you to get A's. I know this takes a bit of self-knowledge but it is important. I can't emphasize enough you want to the adcoms to see this stark dividing line between the old academic you and the new one. The best way to delineate that to them is for them to see a long string of A's at the end of your transcript.
Best of luck.
