Small sample size for villian, but seemd laggy so far.

Preflop call is a little iffy, but the way the table had been playing, I figured I was safe to not have a reraise behind me and some calls making a big starting pot and the implied odds requirement smaller.

Anyways, couple questions.
1) On the turn, is that a push...or is my small raise ok to hopefully string along some two pair or flush draw hand?
2) What do you put villian on with checked flop and huge pot. Options of course are:
-It was a total steal attempt preflop
-Monster letting others catch up
-Flush draw wanting to see the turn
-???
3) Am I good enough with this multiway pot, the check around and action before me to get it all in?
