Hero?

Ever since moving up to 22s, I find myself losing chips in midgame situations like this where the blinds aren't quite high enough for me to go into push/fold mode, but a failed blind steal can hurt me. I guess I have two questions here. Should I have just pushed pf? What if villain and I each had say, 500 extra chips? Villain is 28/13. As played, should I c-bet the flop?
