10nl Deep Stacked, Value ?

This is a deep stacked $.05/$.10 game on Full Tilt with a max Buy In of $20 (200 bb).
I haven't played this type of table before and didn't now how to finish this hand out.
Villian had already doubled when I sat down. Since then, I had seen him take down
several decent pots without a showdown, but he would usually show and then say nice fold.
When showing, he would either have junk or a nice holding, but each time he had what he
was representing.

On to the hand, I min-raised the turn to sweeten the pot and bring him along if he had a
marginal holding like A9 or AT, figuring he would re-raise me hard if he had something much
better. Then he bets into me on the River and I am a little worried about a higher straight.

call turn, hit flush, stack straight.

You have a 1 card low end of a straight. There really isnt much you beat that is calling a raise so I dont like the turn raise. Having said that play throughout the whole hand looks really weak and his river bet really looks like a blocking bet. I have a funny feeling you are ahead of 9T or a set or something, or maybe splitting the low straight. I think Id call it.

My reads throughout the hand were as follows:

Preflop: villain could have any 2

After Flop: I put villain on any PP, ATs, A9s, A8s, 78, 89, 9T, or maybe even missed overs.

On Turn bet: any PP, ATs, A9s, A8s, 78, 89, 9T, AJ, and maybe JT
After my raise here, I planned on betting the River 1/2 pot if he flat called (if board did not pair), If he re-raised small I planned on calling and re-evaluating on river, If he re-raised big I was folding

On River: He didn't re-raise the turn so I didn't think he had a J, but then he leads the River??? Here is where I lose it and don't know what to do. Did I play bad earlier to be in this situation? Does he have a J? I feel like I have to call , just over $5 in a $22 pot. I don't feel like I can raise because the only thing that would call would be a J, but I feel like I played this hand out really weak.

Hero calls $5.50
