BB should have re-raised on flop, especially with hearts out. A3s seems to be getting his money's worth but I didn't chase down the math. I don't believe its possible for 66's to fold since he's only seen you push. 77's Likewise could possibly be getting the best of it. He could have folded maybe (I only play NL50, so don't know) if it were a tighter game but at 25NL he'd be crazy to.

So in conclusion there was only one wrong play and that was slowplaying the flop with a set. This is just one of those minor freak hands, be glad you were on top of the pile.
