Brian has outlined it pretty good if you follow those instructions you will get the job done. A couple of other notes, Buchanan Spokes are first rate and probably the best I've used, some of the less expensive have a tendancy to strectch more. typically spokes are a cross 2 pattern, sometimes you get spokes that require a cross 3 pattern, these are supposed to be stronger than a 2 pattern, all this means is that each spoke will cross 2 or 3 other spokes, so if you try to do a cross 2 with cross 3 spokes they will be to long. As Brian mentioned, anti seize is your friend, not today but later as you need to tighten your spokes. And the offset is so critical, if you go in with no idea your bike may not track straight.
I don't like the stand you for the link that RD posted, or maybe I'm not seeing all of it, but it appears the shaft is floating and since I use a dial indicator to true my wheels I would constaly be changing it even rolling the tire over would cause it to change. The stand I use has fixed points so when tightened the hub stays in a constant position.
Most wheels are extruded and rolled so there is always a spot that is flat where they weld them together, Sun Rims are the truest I've seenm they to are made by Buchanan.
