Horribly misplayed set of tens

Stars $11, first hand of the tournament. Only just moved up from $5.50 (this is from my 3rd $11) so I have even less of a potential read on my opponents.

Final Pot: t2290

If villain has flopped any pair, two pair or a set, he's surely going to be throwing in more than 100 into a 190 pot with that flop. If he flopped the straight, surely he checks or bets less than a hundred, to guarantee some action?

It feels like he wants to see another card as cheaply as possible, I put him on a straight draw and think my set is good. Am I raising enough here?

He comes over the top, but for the minimum amount. Now it feels like I'm being trapped. Should my options at this point be push or fold? I decide to call and then push the turn if the board doesn't get any scarier - which unfortunatley it does. Oh well, there goes half my stack on the first hand.

Please be gentle.
