Some awful hands - plz help

[Atropos]

Hey folks,
I'm trying to learn limit 6-max play, have only played the 400$ NL 6-max games thus far, nearly no limit experience. Of course I read all the important threads in the excellent stickies here but still I seem to suck. Here are some hands, where I didnt know what to do. Plz post a short answer what your line would be.

Party Poker 5/10 Holdem (6 max, 6 handed)

Preflop: Hero is CO with 9[img]/images/graemlins/diamond.gif[/img] 9[img]/images/graemlins/heart.gif[/img]
2 folds, Hero raises, Button calls, SB+BB fold

Flop: (4.80SB) Q [img]/images/graemlins/heart.gif[/img], 3 [img]/images/graemlins/diamond.gif[/img], 3 [img]/images/graemlins/heart.gif[/img]
Hero bets, Button raises, Hero calls

Turn: (4.40BB) 4 [img]/images/graemlins/spade.gif[/img]
Hero checks, Button bets, Hero calls

River: (6.40BB) 8 [img]/images/graemlins/heart.gif[/img]
Hero checks, Button bets, Hero calls

Out of position I always get scared, probably a NL habit [img]/images/graemlins/smile.gif[/img] Should I fold here somewhere, on turn, on river when the flush completes or are my pot odds to good?

Hero bets, Button raises, Hero calls

Button was a huge, very crazy, very aggressive FISH. I have no idea how to value overpair against him.

At the river the pot was huge, so I called with my A-high. On the other hand, I was the one who made the pot big, dont really like it.

Party Poker 5/10 Holdem (6 max, 6 handed)

Preflop: Hero is SB with K[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/spade.gif[/img]
2 folds,CO calls,Button folds,Hero raises,BB folds,CO calls

Flop: (4.40SB) 9[img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/diamond.gif[/img]
Hero bets, CO raises, Hero 3Bets, CO calls

Turn: (5.20BB) T [img]/images/graemlins/heart.gif[/img]
Hero bets, CO calls

River: (7.20BB) A [img]/images/graemlins/diamond.gif[/img]
Hero checks, CO checks

Is it better not to 3Bet the flop so that CO doesnt get into Calldown mode so soon? Reraising at the turn would have got more bets in. Is the river a value bet or rather a Bet/Fold situation than a check-call?

I would appreciate comments on the hands very much. It's possible that there are some note errors in these hands, I typed them all up myself without a converter and went insane after the 2nd one lol.
