I'd second Greg's recommendation for Roger Musson's book - really very good, and includes plans to build truing stand from scrap timber.
The wheels I built with it have done some 2,000 miles plus, commuting & touring.
There's a good one day course in Oxford that is very reasonable.
It's run by Oxford Cycle Workshop Training, and costs £85.
Oxford shouldn't be too difficult to get to?!?
I think the next one is on Saturday February 19th... according to their course dates http://www.bookwhen.com/ocwt
Their website is http://www.cycleoxford.coop
They're a nice bunch. Organise loads of events in Oxford
