Top pair against weird line

[Scipio]

Villain has 25/21/2,8/25 stats and is a tricky 600/1k NL regular. I think he is a solid winningplayer but my samplesize is small. I was relative sure that he allways bet a flushdraw on the flop as well a set. On the turn i put him on 44/AdTx/AdJx or a cheap showdownraise with TdTx,JdJx,QdQx - i considered call, fold and push.

Check flop standard?

I didn´t knew what to do on the River, too.
I have the second best hand in my range here.
