Stars $25NL - KJ on button in multi-way pot?

[jakrpanda]

I got into a strange hand last night and I've been wondering how I should have played it better, perhaps raising on the button and limiting those in the hand, or not at all by folding:

The entire time I played this hand I got a feeling that I was in a pot I didn't want to be in. It wasn't a huge pot, but it was significant because I felt that my moves might have cost me some money. I want my game to improve so I figured I'd post it here and try to solicit some feedback. How would you play this hand?

BTW, I had very little information on villain or any players, this was early into a session and I had seen maybe 3-4 hands.
