I think you have to raise preflop at the limpers, even though you don't have position. JJ is the 5th best hand you can have and the limpers don't figure to have much.

I think checking is fine, but I am not crazy about the push. It is true there are possible draws out there, but a set is a strong hand, and I would try to get action. Just calling makes it too easy on draws, and the action could dry up on the turn if they are on draws or a dangerous looking card hits. Therefore, I would make a smaller reraise and push on the turn.
