Too much?

Thought the river 3-bet was a bit thin but his limp from the SB made me think maybe it was ok. I wouldn't have folded to a cap though so maybe that's enough to tell me not to do it?

The general rule of thumb is to bet/raise on the river when you think you are least 55/60% good if you get called, and that would certainly fit here.

I don't know why you think your raise is thin. Surely he would have raised you on the turn with any hand that you'd be behind to on the river.

I would just call on the river. It's a wierd way to play unless he has the case 8 and you have a pretty weak kicker. he could be bluffing J9 but but that's no reason to raise either.
