Well in a nutshell: During the fight in the alley (shortly after the fade-to-black in NFA), W&H sent LA to hell. Not sure how exactly that works (is it in an alternate universe, or has LA just vanished from the world or what?), but the whole town is now in hell and full of demons preying on humans. There is a poster here that shows Angel on the dragon (they became friends! Squee!) and you can see LA as hell in the background. The stronger demons fought it out, and by the start of AtF LA has been divided into 9 districts, each ruled over by a Lord. Spike & Illyria are co-Lords of 'Beverly Hills'...
ETA: *How* they became Lords is obviously what the Spike-comics are going to focus on. I can't wait! :)
(So you see how Buffy is pretty much not an issue. He *has* plenty of adoring women - especially a woman called Spider - but I can't see him falling for anyone. So far the I'd say that if I were to write Spike with someone, it'd be either Angel, Connor or Illyria.) (Or Spider, but I kinda presume he's sleeping with her already - but as I said, she appears to think the world of him, and he's just wondering how to survive and maybe even get out of hell.)
Spoilers for AtF.
