I've built up several wheels now between hubs and nexus internal hubs.
I just keep re-reading the the sheldon brown wheel building page.
Read what Justin has to say as reinforcement and as it pertains to wide flanged hubs. (below the calculator on: http://ebike.ca/SpokeCalc.shtml
bobc's list is good, though I've never thought about the final 1/8 turn backing off.
I use a long handled smooth sided wrench to stress relieve the spokes. http://www.sheldonbrown.com/wheelbuild.html#seatinghttp://www.sheldonbrown.com/brandt/stre ... eving.html
don't be afraid to bend the spokes in big gentle loops to get them where they need to go. Avoid sharp bends.
Sometimes when I have serious dishing to do on a rear hub I'll put all the sprocket side spokes in from the inside of the flange, rather than in and out as is typically done. I think Justin covers this.
Don't be afraid to take it all apart and do it again. More experience is better.
