Home Game/ Middle set

hey, this occured tonight, just wondering if I could have played it any differently and if so, what?
Home Game 1/2nl but played more like 5/5nl at the end of the night. Hero has about $1000 about beginning of hand while drunk villian has roughly $2000.

Hero is dealt 9c9d. Late position raises to 15(standard), Villain calls, as does Hero. 3 to the flop.

Flop: 9h Qh 4s
Hero checks, late position checks, Villian bets 30. As he bets he goes on to say that he has a set (he's drunk, hes been rambling out random bullshit, plays reallly loose).
Hero calls 30, late pos folds.

Turn: 6s
Hero checks again, Villian bets 100 and says "I'm gunna make a believer out of you that I have a set"...
Hero thinks for a little while and reraises to 400... Villian immediately goes allin for 1500. He has me covered?
Call???

Results to come.
