The cable is standard all though many people say to get the most out of a bb7 you should use compressionless brake cable housing. Expensive. Never tried it so can't comment on how much better it is.
RE: Rotor size. You get a adapter depending on the fork and the rotor size you wish to use.
I think most forks do 160 mm without an adapter but 180 and 203 mm need an adapter, though I would not swear to it.
