set vs passive utg at cp 30

[ship it pls]

utg is tight passive and raises, 4 calls, hero 99 on button cold call... 6 to flop... Jc9s3h... checks to lag in middle who bets, hero pumps it and all take 2 cold... 6 to turn for 2 bets... turn Qh... checks to hero who bets, original raiser says 'what do you have, two pair?' and proceeds to raise... one player takes two and the rest fold... hero? anyone play it differently if we have QJ rather than 99 because its less likely its set over set?
