To be quite honest, I am about to lose my mind with online poker. I just can't manage to put anything together for a consistent run especially on Fulltilt. So anyway this hand came up and I want to know if I could/should have gotten away with some chips or would you guys have done the same thing.

100 players remaining of 400 in a tourny. Chip average is 7k, blinds 80/160.

I am on the button with 6710 in chips

The player 2 off the button with 8390 in chips limps in.

Action folds to me and I raise to 415 with . The blinds fold and the limper calls. I previously doubled through this guy about 8 hands earlier with AA when he called me down with K8 on a 6 10 8 2 7 board. I checked his OPR and he has a 30% rating and is a "maniac" according to Poker-edge.com

Flop comes a beautiful .....perfect for my QQ against a guy who will apparently hold on to a face card for dear life (sarcasm). He checks and I check behind him not wanting to get check raised with his garbage K5 or something like that.

The turn is and he bets out the size of the pot which was ~1000. I am now convinced he called me preflop with a weak A or K and is bad enough to call me down yet again so I push. He calls immediately and flips over . And I am out of the tourny.

I need help because I don't know what to do anymore. I have tried tight play, loose play, passive play, aggressive play......I can't get it together. I know I should want people calling me OOP with 86 when I have QQ but I feel like I am always messing it up. I almost never build a chip stack in a tourny....I just survive until a coinflip comes up or a 60/40. I NEED HELP!!!!! Sorry for the rambling, but I just can't stand it.
