If you have them, the actually hand histories and any reads you have will get you better advice.

In general:
Hand 1: Fold that sh1t. ATs may look pretty to some, but it's not that strong, and certainly not strong enough to call 12x BB.

Hand 2: This is probably a contrary opinion, but depending on how aggressive the table is(lots of preflop action), you could fold this in EP. You limped, which is also fine. The flop bet was reasonable. Once he called and the A hit on the turn I'd probably slow down.
