Tough spot with reraised JJ

Ive only recently started reraising JJ preflop and I didnt really know how to handle this spot.

The first raiser (UTG) is pretty TAG. I actually have him as 15/6 in my database but its a small sample size and I think he was closer to 19/9 at the time.

The other guy (BB) is 45/9/0.7 after another minute sample size although he did show down a hand where he called big bets (and a flop checkraise) with a K9 TP on all streets.

Pre-flop: (5 players) Hero is CO with J:club: J:diamond:
UTG raises to $4, Hero raises to $12, 2 folds, BB calls, UTG calls.

Flop: 9:club: 4:club: 5:club: ($36.5, 3 players)
BB bets $9, UTG folds, Hero thinks something along the lines of "bollocks!"

Questions:

1) Assuming UTG is 20/10 do you like the reraise from this early a position or is the call better here?

2) Wtf do I do postflop after Ive raised?

I cant really raise for information since Im committed if he comes over the top again given that either my J or my club might be good.

I dont want to call and see an overcard (and im not overly happy about a ten comming either).

I dont particularly want to fold an overpair + flushdraw for such a weak bet.

ehhh if UTG is 15/6 normally I don't raise here, but of course that's nitty and raising is fine. I don't see how you can't raise the flop. The problem is of course, once we raise it's impossible to fold. You may just want to push here, if u raise to 30 you're giving a fd and overs odds, if you raise to 40 you only have 48 left to push on the turn.

yea i dont like the preflop action given his position and nittiness.

i would push because i dont think your read is good enough hear to fold overpair with the club
