In my very limited experience that's exactly how I would have played the hand... bet sizing on the flop may have been a little excessive... but at this point I'm probably prone to results orientated thinking...
Reason I say too large is that the flop probably doesn't connect with any of the villains range unless he's got XJ so a small C-bet would probably have achieved the same (To push off hands that didn't connect...)
agree with johnboy, 3 betting and c-betting that amount with that hand almost pot commits you, maybe 3x instead of 4x pre then under 1/2 pot bet on flop
