NL25 JJ gets reraised preflop and hits bottom set

[Timba]

hi, first of all im from germany so please excuse my bad english. i would like to get some opinions on this hand. i dont use pokertracker so i cant post any stats.
my opponent was playing very tight so far, this was the first time he made a preflop reraise.
i have two questions about this hand:
would you reraise him again preflop and is there any way to fold this hand after the flop? <font color="white"> </font>
