Calling is fine here. Usually I'm looking for a stack of 10x the raise amount (with both, my stack and villain's stack) to get the odds to play for a set.
Both villains have a stack lower than 7000, but since it's a multiway pot, hero still gets odds to make this a +EV call.

I also like the raise ... but once you raise, you have to go with it. So either push right here or raise to 2000-3000 and shove any flop.

I would go for a 2500 raise and a shove on the flop, as this would give villains a chance to fold bigger PPs because of overcards or fold 2 unimproved picture cards.
