First tries at 25-50

I think so too, especially given that you have a hand that has a solid shot to win a showdown (vs straight or flush draws).

Pure bluff on riv on that board to get 88 or TTish to fold? I don't know, doesn't seem like you have a good enough read on opponent to think he'll lay it down often enough for a bluff to be profitable. I'd advocate that you bluff more likely if you had a hand like 5 6 with no shot of winning a showdown, because not only does he have a chance to fold an overpair but also a draw hand that could show down queen high and win the pot.
