How do I play this KJo? PS $215 hand

[ClaytonN]

Mathematically I was still unsure where I was. I was getting 7:2 on my call, but at the same time my hand still might not be good. BUT, at the same time both those guys limped.

1) How to play the flop?
2) Assume you played the flop the same way I did, do you call this reraise all-in?

I did some math in my head and figured I was getting about 3.5:1 on my money. Is this accurate?

I lay it down. And I don't think I would bet the flop either.
