real right quarter panel fix

Ok so i was parked on a steep driveway and when i went to released brake, i wasn't fast enough to rev and my rear right hit the wall behind :shock: So when i look at my passenger door gap line standing 5 feet behind, i see the door line sticking out by maybe 2/16'' . Just wondering if i can flush it by taking out rear right quarter panel and fixing it myself or is it a body shop thing? Also, i noticed my right rear 5mph bumper tube thing is also pushed in by bouts 3/4''. Can i pry bar it back to original lenght or is there some other way of fixing it?
