those 3 cog stacks are hard to come by. but! you can, however, stack two sturmey cogs on one hub, bulge portions together (with a thinner than normal spacer between), and snap the circlip on. thats how i usually run mine for touring with any real climbing involved - 2 sets of gears that way - one for flats, and one for climbing... manual gear change, but it only takes a minute once you have it down.

id put my money on it being the spring cap - little bit that goes on top of the clutch spring, with reasonable odds of being ejected by said part upon disassembly...not absolutely neccessary... ive run hubs without them, and some aw diagrams dont show them.

as for places that service them, i dunno - i do all my own work, but im not confident enough to say ill work on someone elses :) can definitely provide parts locally, though, from my stash of dissected old aws... pedal revolution and american cyclery (both in sf) i know to have various spares.
