Could I have gone broke differently?

[feelixthegreek]

I went out early in the $200 tournament at Harrah's yesterday, and of course I'm left wondering where I went wrong. Which brings me here.

I've got T1025 and the the blinds are 25-50. Folded to me in MP1, and with TT I make it 150. Player on my immediate left, who was a few hundred more than me, calls. Folded around.

Pot is 375. Flop is 863, two hearts. First to act, I make it 250 and get flat called. (Should alarm bells have gone off here?)

Pot is 875, turn brings a 4, not a heart. I've got 625. I bet 325 and get called again. (In retrospect since I was committing myself I should have pushed.)

River is a Q. I throw in my last 300 and get called by JJ.

My intial feeling was that he played the hand as badly as I did, since he was willing to call off his chips not knowing where he stood. But I wonder if I was simply too aggressive with TT so early in the tournament. Or was I too passive? Or the perfect combination of both?
