I think the only thing that's clear here is that you should have limp/called the flop instead of limp-raising. You've got high cards with a big pair (pretty much what they think you have) and you're still deep enough to have a lot of play OOP.

As played, I'd probably just check the flop. Middle set's unlikely since you have a queen and you're not going to get called by anything else that you beat. Also, it's a multiway pot and live players are more likely to call a weak flush here as well as more likely to check the nuts, especially if this is at the WSOP.

If you are going to bet the flop, I'd probably just pot it rather than leaving most of the money to be bet with one card to come and allowing a flush to play more correctly against you.
