Pre-flop help

[chucklhead]

Howdy,
I have been taking a beating at $1/$2 Planet Poker. In this case a beating is down $100 over two days. The game is tight, but I would like to learn how to beat a tight game. Tight in this case is 30-40% seeing the flop, average pot size is less than $10. I think I might be misplaying preflop a little. Here are ten hands which I am wondering about. For the sake of arguement, the only thing I know about the players are that they are playing in a way that the table has the stats it does.

1) QJo on the button, one early and one middle limper, I call.
2) T9s late middle, one early limper, I call.
3) 44 middle, folded to me, I fold.
4) Q5s small blind, UTG raise and late middle called, I fold.
5) Q9o on the button, 2 early to middle callers, I fold.
6) 56s in cut-off, folded to me, I fold.
7) A5s on the button, early call, middle raise, cut off cold call, I fold.
8) 44 in cut-off, one middle caller, I fold.
9) KJo in middle, 2 early callers, I fold.
10) KTs early, folded to me, I fold.

Any discussion would be appreciated.
Thanks,
Chucklehead
