Decisions... decisions... What would you do? #6

I continue to get into decisive situations more often at the $50 level... Here is a WWYD situation?

UTG+2: $30.85
MP1: $67.70
MP2: $60.60
CO: $50.00
Hero (BTN): $58.35
SB: $60.30 - 28/22/1.0 @ 46 hands
BB: $45.00
UTG: $50.00
UTG+1: $18.25

Pre Flop: ($0.75) Hero is BTN with Jc Js
5 folds, CO raises to $1.50, Hero calls $1.50, SB calls $1.25, 1 fold
CO proved to be fairly tight. Therefore, I'm not sure of whether my JJ is ahead, but I'm at least calling in position.

Flop: ($5.00) 5d 9d 5s (3 players)
SB bets $3, CO folds, Hero raises to $8.50, SB raises to $14, Hero calls $5.50
On the SB lead and CO fold, I'm fairly certain I'm good - therefore I raise. I'm not so sure of what is going on here, though... I don't like that 4 bet on the end.

Turn: ($33.00) 4h (2 players)
SB bets $10, Hero requests TIME, Hero calls $10
Okay. I'm nearly folding here. It totally smells of value bet. I thought long & hard about this - I will nearly have half my chips into the pot. In retrospect, I should have shoved or folded right here. However, the question is: Do you make the call?

River: ($53.00) Kc (2 players)
SB checks, Hero checks
I am OVERJOYED to see a cheap showdown!

Final Pot: $53.00
Hero shows Jc Js (two pair, Jacks and Fives)
SB shows 7c 7s (two pair, Sevens and Fives) - I had to type to him in the chat window (don't think he thought I was genuine though, although he almost did win with the worst hand) "NH"
Hero wins $50.35
(Rake: $2.65)
