Should I be raising PF? Bet the turn too?

Also the second hand of the tournament which crippled me:

Me: AK
Blinds: 10-20

Raise to 80 PF.

2 callers. Flop is TJQ, all different suits.

Excellent, have the nuts, checked to me, I bet a low 100 (mistake? thought I would get some money out of this).

One caller.

Turn 2, checked to me, I bet the pot (good right?). He calls.

River, T.

Board reads: TJQ2T , no flush. He checks, I move all in for another 925 (pot is around 1400 I think). He calls and shows QT.

I have 100 chips left now, 2nd hand of the torunament.

Where did I go wrong?
