The Stans rims are very very nice, but also very very expensive.
For something a bit more affordable, but still very high quality, look at the Mavic TN719 rims. They're 25mm wide (so not quite as wide as Stans or Bonty, but still a decent width), bang on 500g each in weight (not too bad for a 29er rim) and they're eyeletted too so should last ages. Oh, and I'm running mine tubeless too. Ghetto was easy enough, just used a 24" inner tube slit down the middle, put the tyre on, in with some sealant, and pump like crazy…
Tyre wise, at the moment I'm running some 2.2" Kenda Nevegals, which incidentally are BIG for a 2.2". They seem a pretty good all round tyre, not great in the deep mud like a Mud X say, but they just seem pretty good most of the time. And as I said, they're big, so add an element of cushioning too. To be fair though, they might end up being swapped for some Bontrager Mud X's in 2" flavour sometime soon, at least until some of the mud starts to dry up…
