I could be totally wrong on this but I believe ASFs are illegal in some parts of the States or entirely? Not sure, I haven't looked into them too much and it's been a while since people have talked about them on the mouse forums I'm on but from what I remember there was some sort of legal issue which is why they aren't too common in the fancy any more.
Generally speaking, the main reason people get ASFs is so male mice can have friends without any issues with neutering, mating, or territoriality. It's pretty uncommon for someone to put, say, male ASFs with female mice. So, you would probably get a male mouse and 1-2 females.
In terms of wheels, mice/ASFs don't need wheels like hamsters; in fact they're entirely optional to begin with. You can start with one or two and adjust from there depending on how many of your mice/ASFs actually use their wheel (for example, I have two mice right now, but only one of them runs on her wheel at lot).
As for food, I'd assume you could just feed rat/mouse food to ASFs. Mice and rats have very similar nutritional requirements to begin with right down to the recommended GA.
Overall, though, I'd recommend posting this on Pet Mouse Fanciers. I believe there are a couple people with ASF experience on there or are at least more familiar with their care.
