$22 early - TT in BB, four limpers, re-raised when I pop - Hero does?

[jedinite]

Curious what everyone thinks the correct action is here.

SmallBlind has one won pot so far - they chased and caught the nut flush (with no full house or SF possible) on the river, were bet into by the person who lead the flop and the turn, and this person only called with the nuts. So I immediately give them a note that ammounts to "probably inexperienced".

Here's the hand:

Bonus question - was the raise preflop wrong?? Raise bigger or not at all?
