I went with Velocity's Synergy OC rims for my touring/commute bike. I feel much better about using a 700x32 or 700x35 tire on these wider rims than I would on something narrow like a Deep V or Open Pro. They're not quite as wide (or heavy) as the Dyad, so you can still squeeze a 700x28 or even (I think) a 700x25 on if you want a "faster" tire. The off-center drilling leads to more even spoke tension, which should improve durability.
I wanted to use disc brakes, so I went with mountain bike hubs. Found XTR hubs on sale for less than the cost of XT, so that's what I went with. I ended up with 32 spokes in front and rear, because that's the only version of the hub that was available. Given my choice, I probably would have gone 28/32 or maybe 32/36 if I were planning to carry a very heavy load.
I always use brass nipples. Aluminum nipples are just too easy to round over, even if you're being careful.
I went with DT Competition double-butted spokes.
