looks good. I'd bet 1/2 the pot on the river though because you will often face lower J like JT or JQ, especially at low stakes NL games.

I like the river check behind in this case. The villian has 0.50 cents or so, so there could be an argument for the all in push, but I doubt he folds considering his flop and turn play. Also, since there was no preflop raise, villian could be holding anything. I think you played it well.

Pretty standard, might value bet river.
