Bad time to raise for a free card?

[lightw1thoutheat]

hey, this happened last nite,
MP2 is 33/4, Button is 44/0 (only 15 hands), SB is 41/13, BB is 26/4

How is this line? I was able to get the pot HU on the flop which was nice. Should I have bet the turn? or checked behind? Also, is the flop raise a bad idea to figure out where i stand, and to limit the field?
