I think the pf raise is fine. You often steal the button and are ahead of MP1 and MP2 enough for this to make sense.
I don't think QQ+ is a big part of SB's range. If he's TAG, he has to 4-bet those hands with the original raiser and caller left to act. Otherwise, he's looking at playing 4-way OOP. The cold call of the 3-bet screams pp, big A or suited A (maybe even not that from a TAG). There may be other SCs in there too but nobody else is very deep so does he really want to play those?
Flop bet is good. You can't call the raise, obv. This is really close depending on whether you think he can do this with 88-TT as well as his sets and Axss. If he is a reg, is he capable of doing this with a small overpair or FD? If so, then I shove and probably shed a tear...
