I see that most (probably all) of your questions have been answered already, but I thought I'd interject my own opinion as well.
As to how I feel about using fanon: it depends what sort of fanon. I don't really like the Liam O'Connor bit, because it just sounds so blatantly Irish, like the writers are trying too hard. I do use the fandom word "childe" though.
As to Spike's last name, I've seen "Sullivan" used a few times, and I like it. William Sullivan is a good, realistic name, plus boys called Sullivan were sometimes nick-named "Spike," so it could work that way too.
The Age Of Spike is something that I try not to think about. I just say "approximately one hundred and thirty" and leave it at that.
Vampire sweat and breathing: If you've noticed, Angel breathes a lot when he's freaked out or in pain, in fact, he nearly hyperventilates. I think it's a left-over reflex from his human years, unnecessary, but habit. Same with Spike's breathing. Also, vamps have to inhale in order to speak or to smoke, so yes, they do breathe, even if they don't have to. They sweat, too. They shouldn't, but we see them do it, so it must be true.
As to how vamps get it up: well, they're supposed to have no circulation, but that can't be true because they bleed when they're cut, and if their blood didn't circulate then it would all pool in places like their shoulders and bottom when they lay down for a while, like blood does in human corpses. So I think the general consensus is that their blood circulates very slowly (it's a mystical thing, best not thought to closely about it, like Spike's age or the fact that Angelus can grow facial hair but Spike, even when he gets captured for long periods of time, doesn't even grow stubble).
If you're looking for Andrew het fics, google "Funnel Cakes and Flying Monkeys," the Andrew fiction archive. Some links to it are dead, though, so you have to look around for it.
Angel wears eyeliner in fics? Really? Why was I not aware?
