Live 3/6 JJ on the BB

[Meraxes]

First rotation at this table, but it seems typically LP. No specific reads on individual players.

Hero is delt J [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/heart.gif[/img] in the BB
Preflop: 4 limpers, SB completes, Hero raises, everyone calls.

Flop (11 SB): K [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/spade.gif[/img] (6 Players)
Hero bets, 2 callers.

Turn (7 BB): 8 [img]/images/graemlins/diamond.gif[/img] (3 Players)
Hero checks, checks around.

River (7 BB): K [img]/images/graemlins/diamond.gif[/img] (3 Players)
Hero checks...

Mainly two questions: should I just c/f this flop? and do I value bet this river?
This probably seems like a simple hand, but the texture of the board made it not obvious for me.
