6th Hand - Should I have slowed down?

[goldtoes]

6th hand of a $20 MTT. Obviously don't have a read. I am mainly worried about how I played the turn. Should I have just called his turn / river bets instead of raising and reraising AI? The more I look at it, the more I think I overplayed the hand, but how standard is it?
