bottom set facing 2 all-ins. Odds to call?

Party 30+3, about 15 hands in.

MP probably plays his made hands a little more strongly than he should but nothing too ridiculous. If he's calling a re-re-re-raise all-in, let's give him credit for KJ. No read on SB. At best, I'm against two made straights or a straight and a flush draw.

My equity:
vs KJ and QT: 11%
vs KJ and J8: 35% (30-31% if either of them is suited in spades)
vs KJ and KQ [img]/images/graemlins/spade.gif[/img]: 31%
vs KJ and TT: 5%

There's also the miniscule chance that I'm up against something wacky like A5 [img]/images/graemlins/spade.gif[/img] and QJ, but I don't think that happens often enough to matter here.

I'm getting 3.5:1 on my call. I need to win about 29% of the time to make this +chipEV. The side pot with the SB would be fairly small (228 chips including the ones I'd put in), but of the two it's more possible he has a flush draw or 2 pair. I stand to win a little more often against him than I do against MP, so I can probably bump that 29% down to 26-27% or so. If I call and win I have over 3000 chips and 3x the next stack, and I've been feeling good about my big-stack play as of late. If I call and lose I'm left with about 450, which is certainly playable at 15/30 blinds. If I fold, I'm left with 1150 and I'm second in chips behind whoever takes down this pot.

Is this a call? If not, what odds would you need? Also, how's my reraise on the flop?
