I had 5:1 pot odds and I figured very good implied odds with the Big Raise and 3 limpers. Since it's Level 2 is it too early to call off ~1/7 of my stack for a set even with these odds?

The preflop raiser is going to act immediately after me. I put him on an overpair with such a big raise preflop and he'll probably come over the top of the short stack's all-in. Should I slowplay with the two diamonds with the button remaining after the preflop raiser? I don't think two diamonds will be in Button's hand with a big preflop raise. Probably mid-PP for the Button.

I think the preflop call is a little thin, and I'd probably fold. That said, I think it's resonably close with that many limpers and you closing the action here.

Theres a lot in the pot already, and theres no way the original raiser will lay down an overpair to your push here. I shove and make it as expensive as possible for anyone drawing.
