Big Multi-way Pots w/ Big Draws for me: What's your line? 3 Hands

[tagtastic]

Hand 1: SB is pretty donktastic (results show this too), I have no idea what he has, but I'm really not that concerned with him. Button is a good player.

I called SB's bet, and Button raised to $55, SB calls, action on me again.

Hand 2: UTG I thought highly of before this hand, afterwards my opinion of him dropped significantly, but either way he's fairly tight/aggressive. SB is good and CO is terrible (preflop raiser in this hand), he'll raise like this way too often with crap. This hand created alot of controversy at this table afterwards.

Hand 3: UTG is retarded, raising large preflop very often, no one has respect for his preflop raises (that's why I'm in this hand w/ a 7xBB raise). Button is solid. I bet 2/3 of the pot ($19 into $29), UTG folds, Button pushes for $115 now what?
