$11 - Check my line on two hands

[WiredPear]

I really misplayed these two hands. I'd like to hear some feedback on my line:

Full Tilt Poker : $10 + $1 Sit & Go (4449394),
Blinds 60/120 - No Limit Hold'em
7 Players left

Hero has 1,290 - in the big blind
Villian has 2,405 - on the button

Villian has played very solid; hasn't been out of line at all so far.

*** HOLE CARDS ***
Dealt to Hero [As Th]
4 players fold
Villian raises to 240
SB folds
Hero calls 120

Pot is 560

*** FLOP *** [Td 5c 2d]
Hero checks
Villian bets 360
Hero calls 360

Pot is 1,280

*** TURN *** [Td 5c 2d] [Kh]
Hero checks
Villian bets 840
Hero calls 690, and is all in

The obvious mistake was either to fold or push on the flop. Calling was just stupid. I was thinking about villian's holdings and worried about an overpair. I called before looking at the pot, etc. What hand do you have villian on? How would you play this hand differently?

HAND 2

Full Tilt Poker : $10 + $1 Sit & Go
Blinds 20/40 - No Limit Hold'em
9 Players left

Hero has 1,620 - UTG + 3
Villian has 1,550 - UTG + 4

It's still very early in the SNG. My only read is that Villian seemed tight. But it was still early.

*** HOLE CARDS ***
Dealt to Hero [Qs Qh]
3 players fold
Hero raises to 120
Villian has 15 seconds left to act
Villian raises to 240
4 players fold
Hero calls 120

Pot is 540

*** FLOP *** [9h 5h 5d]

Hero bets 340
Villian raises to 900
Hero ????

I gave serious thought to another pre-flop raise. But my read was AK and I was out of position. My plan was to just call and then bet the flop if it didn't have an A or K. What hand do you put Villian on? Do you fold the flop raise? How would you have played this hand?

Thanks for the help.
