Spoke Size / Spoke Length Database - What size spokes do I need?

Any update on this - did you get them built OK?

Cheers guys, 292mm DT Competition ordered. Will let you know the outcome. This is my first wheel build so I am pretty excited :-)
I have a truing stand, dishing stick and spoke tensiometer, as well as spokeys. But I am little bit confused, I've also heard of a "nipple driver" - do I need this, or can I use something I already have in my toolbox?
