Another vote here for Sugar Wheelworks. I build my own wheels, but started down that road when former owner Jude Kirstein taught me how in a class at Sugar. They're now part of Breadwinner Cycles, and the go-to source for quality hand-built wheels in Portland.
Regarding rear hubs, I have 2 bikes running White Industry T11 hubs, one with easily over 50k miles on it, and they have been fantastic and maintenance-free. On the hub noise spectrum, I'd say they're slightly louder than my DT Swiss 350, but not as loud as my Hope Pro 4 or Pro 5 hubs (which I also love), and those aren't as loud as Chris King's "Angry Bees."
If you can find an XTR hub, those are among my favorite quality quiet hubs - I've built 2 rear XTR wheels on used hubs and they're pretty sweet and nearly silent.
