Set, so-so board, aggression (tea with that ?)

[sourbeaver]

First off, on this kind of flop with bottom set, do you consider yourself drawing when someone shows aggression ? Reasonable hands I beat are 89, top pair and pair+draw.
I repopped the flop because I didn't want two opponents to the turn (is that good?).

What would you do with no boat on turn ? What would you do on flop ?
