2 Hands from Party $109 - How's my line?

Can you guys check my line on these two hands, which occured back-to-back? I didn't have any strong reads on any of the players in the hand with me.

Thanks,

BM

Edit: I guess my main question with the first hand is whether or not you all would fold after the double all-in.

For the second hand, assuming you felt very strongly that you were looking at something other than a pair bigger than 44, would you call the all-in?
