I don't know JACK about FG/SS hubs, however here is what I would suggest for the rest:
-36 hole Velocity Deep-V rims (36 hole hubs, too...of course)
-Double butted 14/15ga stainless spokes from DT, Wheelsmith, Sapim. I use Wheelsmith myself, but I think all three of those brands are good. Someone might suggest straight 14ga spokes, Those would probably be fine too...
-BRASS nipples. I'll never use aluminum.
Have them built by someone who knows wheels. Maybe get a hold of Peter White (http://www.peterwhitecycles.com/Wheels.asp
) although he is maybe a bit pricy but, he guarantees no broken spokes...
That is all I got for ya
