0.5/1 JJ vs OC flop

[grounder]

SB has been playing LAG
45/16/2.23/264

UTG is the most amazing calling station, J-high is the nuts! Cold-calling 3-bets means nothing, regardless of hand.
90/5/0.23/96

I'm looking for help on pre-flop and flop.

Stack sizes:
UTG: $26.62
CO: $20.80
Button: $15.38
SB: $72.50
Hero: $33.50

Pre-flop: (5 players) Hero is BB with J[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/diamond.gif[/img]
UTG calls, CO calls, Button folds, SB calls, <font color="#cc0000">Hero raises</font>, UTG calls, CO calls, SB calls.

I clearly have the best-hand pre-flop. I should be raising to make the others pay to see the flop despite being able to see a free flop right?

SB had been playing LAG, c/r OESDs, betting APOTB etc. I hadn't seen SB lead out against a PF raiser, however. The calling station will call down APOTB even if I make it 2 bets. With 2 behind is this a standard fold?
