I think you did:

1) You're up against the chip leader, it won't kill him to try and bust you
2)He's actually a LAG player if he's calling allins w/KQo
3)JJ is really just a mid pair
4)You still have 25BB left, not desperation mode yet

In this situation I'll just call the reraise to see the flop. If you think you could have laid it down when that king hit, you bet and he raise you then you have just learned something about playing him. If I'm in desperation mode (sometimes as high as 12BB in home games), it's an easy push. I think point 4 is the swing vote that lets me just call preflop.

edit: Your preflop raise wasn't quite large enough. From what I gather, I would have preferred to see an opening bet of $12-15. This shows more strength and basically commits you to the pot *if he reraises you*, making the push decision correct.
