6 Max - Is this a good iso raise or just LAGY?

[aargh57]

Just started playing 6 max so I'm not sure if this was a good play or not. I'm playing at Prima so I'm not going to write out the whole HH as I'm only concerned with my preflop here. ($2/4 btw)
5 players
UTG limps, CO folds, button raises
Button has a pf raise of 12.33% and I'm in small blind with KJos. I reraise to try to get BB and perhaps UTG to fold. Was this a good reraise or should I have just called original raise or folded?

Also, are the general guidelines for 6max as far as VPIP,PFR%,&AF posted somewhere? Thanks.
