Live, fishy 2/2 game with a lot of action, Hero is about 200-250bb deep.

Hero has T975 offsuit and is HJ.
It is limped around to the BTN who pots it - would you l/call here, or is this hand too weak to fill up?

Flop comes 863s and the BB pots it to 128 - its folded around to hero who has about 400.
Is the normal play here to fold against sets/FD's + SD's, or would you call once more?
Would it be different if Hero has 800 instead of 400 behind?

I'm looking forward to your opinions!
