Short Stacked - All In Correct Here?

[666shooter]

PokerStars $5+$1, around 400 people out of 1385 left. Average stack for the tourney at this point is around 5500 chips, blinds are about to go up in 4 minutes (currently 100/200). I think the biggest stacks of the tourney were up in the 20K-30K range.

I'm being offered 5.5-1 pot odds. The pre-flop raise was not out of the ordinary, that player was aggressive and was capable of raising with a variety of hands in that position. So I think I'm at best up against high cards. I call because I think time is running short, I'm short-stacked, I'm getting good odds, and I have to make a move here with the blinds moving up if I want a chance at all to get back in the tourney.

Hero checks, UTG checks, <font color="#CC3333">Button bets t600</font>, <font color="#CC3333">Hero raises to t935</font>, UTG folds, Button calls t335.

I'm 1.9 to 1 to hit the flush (which I think will win the hand) by the river and pot odds are 3.5 to 1 right now. If I call, I'm only left with a couple chips so I figure I'll put it all-in with the button more than likely going to call. I can either triple up here or die trying.

Does this all look OK to you?
