Two low pp hands from Stars 3+r

[11t]

I am working on my multi game right now so comments are appreciated.

Hand 1: Is this too early a position to be raising 77 from? My image is fairly tight but I have been very aggressive. Villain is pretty LAG. Due to the overbet, I put villain on AK/AQ. This is the correct call, right?

Hand 2:

This is like 3 out of the money and the pfr had been getting a little frisky. I really have no concern about just cashing so considering his range could be pretty wide is this also a correct push even though I am likely facing overcards and am almost surely to be called?
