two preflop spots

I never cold call in the SB, this is the first time i can remember doing it but it seemed like the spot to do it. Didn't think a squeeze would get through multiway vs fun players and i didn't feel like i could fold. In the second hand with 77 i have a feeling this should be a call after 2 calls in front of me but im not sure. It's an unusual spot so i guess it doesn't really matter but is this way too nitty?
