$100 live spread limit, how's my flop line?

[SumZero]

2-2-4 blind structure full table.

Stack sizes were about:

Button $88
SB $181
BB $60
UTG $900
Hero $250
MP $250
LP $250
CO $100

UTG is loose and lucky; Button, MP, and SB are solid; CO is an idiot (just last orbit called a good sized all in bet with 47o pre-flop).

Hero is dealt K[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/club.gif[/img] in EP. UTG limps, Hero limps, 2 folds, CO limps, Button raises to $15, SB calls, BB folds, UTG folds, Hero sees CO counting out the call and calls, CO calls.

Flop ($64 post rake): K[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] (4 players)

SB checks, I bet $30, CO called, Button moved all-in for $73 total, SB calls $73, I re-raise to $173 total...

So ignoring the loose limp preflop, how's the post flop play?
