The man Dean sees in the mirror look to be the same one who is later shown lying on a floor dead. Since Dean beat up Cas, he probably has flashbacks of the people he has hurt.
The man was probably a bad guy but still human. So Dean fed the mark.
Looks to be the same guy. The vamp that was shown I would guess is the headless dude on the left, but the other guy still has his noggin, so he wasn't a vamp.
However, if Deans having conscience flashes like that of Cas and this dude, chances are he was a good guy. With it being a vamps place and a girl tied to the bed, maybe this guy was a hunter trying to help her, but Dean killed him anyway?
If he was a bad guy, not even pre-MoC Dean would care enough for it to weigh on his conscience.
