Harry Rowlands is supposed to be the best. Open Pros are the "standard" for racing rims but I don't like them; not laterally stiff enough and not very round either, especially at the joint. Try DT or, if they're too expensive, Rigida rims. Even my bottom-rung Rigida Nova rims (a tenner each from fleaBay) built up well and took decent spoke tension without pringling.
In terms of spokes, DT Competition are all you need but if someone else is building them, I'd be tempted by DT Revolution.
