You should be able to walk and chew gum at the same time. Remember, the goal of your GPA salvage now is to demonstrate that the you of now is not the you of then, and that you can handle a med school curriculum. Med school will be tons harder than anything you have taken as an UG student. How can you prove yourself to us if you're only taking part time coursework? How can you prove it to yourself????
Your sGPA is well below the median of most MD schools; in fact, it's below the 10th%ile, unles syou live in a lucky state OR you have a massive rising GPA trend. The cGPA is below median and won't get you into Yale, but will do for Drexel/Albany class schools and your state school. A 510 MCAT is pretty much median for MD acceptees.
Your stats right now are fine for any DO school, including mine.
