Final Table Conundrum

[soxfan70]

8 handed final table with the top 5 finishers getting paid; 4th and 5th basically get their money back. Blinds are 400/800, and I have roughly $8500, which puts me in about 4th or 5th place. There are no huge stacks at the table, and two very small stacks. On to the hand -
Two limpers to me on the button. I look down at 4 [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/heart.gif[/img], and limp as well. SB folds, BB checks. The flop is 5 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/spade.gif[/img]. SB checks, BB pushes for his last $3500. All limpers fold to me. I now have roughly 7700, and the pot is $6700. My thought process is this:
1) This guy is a fairly solid player, and would make this move(considering his small stack size) with any two cards.
2) I'm getting close to 3-1 if I call.
3) If I'm behind to top pair, I have 10 clean outs
4) If I call, I'm closing out the action (no one behind me)
5) If I call and lose, I'm not crippled
6) If I call and win, I'm in very good shape to win this tournament.

My questions to all of you are these:

1) Do you agree with my thought process
2) What would you do and,
3) WHY??

I'll post results later.
