88 and AQ, tough spots

[Stork]

both at 3/6 6-max on ub, no one playing particularly wild or anything, no pt up:

First hand: MP raises, button cold calls, I call in sb with 88. bb calls too.

flop: 5 5 2 rainbow
checked to mp who bets. button calls, i call, bb drops.

turn: 7, putting two to a suit.
checked again to mp who bets. button drops, I raise, mp 3-bets. is this a standard call down, or should i let go?
----

second hand: I raise AQs in the sb after a couple MP limpers, 4 to the flop.

flop is As Ts 8c
I bet. BB folds, limpers call.

turn: Kh
I bet, both limpers call again.

river: 6c
I bet. First limper folds, second one raises...anyone fold this getting some 11-1 odds?
