Did I play these correctly ?

I'm in the process of moving my game almost exclusively to .50/1 NL . I'm finding that I can hang at this level.

Down to 6 handed.

I have K[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/club.gif[/img] in MP.

I raise to $4 preflop.
2 callers.

Hero has $90
SB has $173


I have a tight image at this table. SB has only put his money in with very good hands. Straights/full houses

Flop: X J[img]/images/graemlins/diamond.gif[/img] T[img]/images/graemlins/spade.gif[/img] pot = $13

SB bets $4.50
EP folds
Hero raises to $15
SB reraises All-in $167
Hero ?

I chose to fold. I put villain on at least two pair. This game is very loose. Donks are in abundance. I think he believes that I will call so I fold.

Hero AA
Same Villain as earlier

Hero raises to $4 preflop
2 callers
Flop: 7 4 4 pot=$12
Villain checks
EP bets 1.50
Hero raises $10
Villain calls
EP folds

Turn: 5
Villain checks
Hero bets $20
Villain calls

River: 4
Villain checks
Hero bets All-in $70
Villain folds

Would you move all-in here ? He had already put $30 in so I figure he might feel so pot committed that he calls.
