See, what you said makes sense, but they never mentioned anything about new bullets or needing to conserve bullets or anything. Dean's Crossroads Demon did say that it wasn't the "original" Colt, which makes me think that Ruby altered it somehow so that it worked with any bullets they put in. At any rate, it's gone now, so I don't think they'll be clarifying that anytime soon.

I would say that (in my headcanon, at least) they can theoretically be resurrected, but that nobody cares to do so--most angels either wouldn't bother resurrecting abominations and others don't want to disturb the re-humanized demons' peace, Lucifer hates them so good riddance in his mind it's less work for him when he kills them all later, other demons don't want them coming back to boss them around/kick them out of their new position in the hierarchy/torture them, etc., etc. I just really, really like a lot of the demon characters, so I'm always trying to fanwank justifications for bringing them back in my fanfiction. The one I like best right now is Lucifer realizing that he needs more back-up (since he's one archangel up against the entire Host of Heaven) so he brings back everyone he figures is on his side--Lilith, Alastair, Azazel, Uriel, Ruby, etc. Which isn't really nice to do to the poor Winchesters, but, eh, they can handle it. And it gives them more opportunity for revenge. And I miss those evil little bastards.

I can buy that; after all, if you become a demon by losing all your humanity, that probably shaves off all the important (read: human) bits of a soul and leaves... something else... behind. Something not quite human, and thus not quite a soul. I'm sort of on the fence about whether I go with that or whether I go with the Gehenna thing, because both make sense to me for different reason. Depends on the day.

I certainly hope the knife doesn't destroy the host's soul, or else that's a lot of destroyed souls at the hands of the Winchesters.
