I would have played the flop exactly the same way. I like the bet with bottom pair + good flush draw in a large pot. I also like the call (I can also see capping to try to thin the field, but probably wouldn't have). You're getting 9.25-to-1 from the pot, and you have 11 outs (flush draw plus draw to trips), giving you 3.3-to-1 immediate odds, making a call correct.

I like the check-call on the turn, but again I can see betting in order to let someone raise to get others out.

I would probably have bet out the river, or possibly check-raised. I would not have simply check-called because I think you win here more than 50% of the time (probably well more than 75%), far more than your approximate 20% equity on the river.
