Couple points:
1) I mean no offense, but playing set minded here is absolutely the wrong way to think about the situation. Your implied odds are not even close. You will hit your set 1/8 times on the flop. At this stage in the tournament, sets are not important unless two big stacks are dueling.
2) A stop and go does not work unless you are in earlier position and will act first postflop, which could allow you to make 7s-9s fold or possibly 10s. Raymer made an interesting post about such a play, but this situation does not fit the bill.
3) When it gets close to the money, with relatively large blinds, and a mp raises and someone calls, it is significant. Your stack is not large enough to get them to fold at all, and I think you should try to open raise on another hand.
