Spot on.
I've played a fair few live MTTs, cbetting is very important IMO. It works fairly often if you cbet against the right players (don't cbet people who are clear calling stations), and those who are better players will realise you're cbetting every flop, just in time to pay you off when you flop a monster 
EDIT:
Also, low pockets are your new god. I only ever fold low pockets to a MASSIVE raise, or to a 3-bet. If someone raises preflop, your implied odds when you hit your set are HUGE because they will often hit top pair or overpair.
