Just remembered, when i did my first wheels I also bought this online book
http://www.wheelpro.co.uk/wheelbuilding/book.php
It has pretty much everything you'd need to know about wheel building, unless you want to get onto the rather obscure lacing patterns like ********** or crows feet.
Only other thing i would mention is that i did buy a spoke tension meter, which made the job a LOT easier (and by the time i finish my 3rd set of wheels will have pretty much paid for itself already). I just do the basic lacing, tighten up to the required tension (checking with the meter), a bit of truing and the wheel is done. Not bothered with a truing stand, but the book above has blueprints for making your own. I just use an old frame with some cardboard taped in the right places.
