25NL - QQ vs possible nit + flopping trips with Q9

[goshax]

Hey first post,

CO looked like a nit was 7/5 but only had about 50 hands on him so it was not really representable.

Good fold or not? Figured he could have had JJ with a heart or Akh. Don't think he would just flatcall preflop with AA or KK. Maybe AQhh but he was so tight he might have folded that.

Second hand is in a limped pot against two very loose fishy opponents who a were limping from utg etc. They were around 45/10 and 60/5.

I flop trips and check to let them hang themselves(not sure this was right). However after bet and reraise should i pump it to 9$ here or would that be just a dead givaway of my hand? I dont want to scare an Ace here. Money goes in good but I am unlucky on river(not really relevant here i guess). Any thoughts? Thanks
