Hmmm... I hadn't thought about wind-up of round spokes. My latest builds/rebuilds have been with oval and bladed spokes. What a hassle, but I found that I can pretty much build the wheel, then deal with wind-up.
As far as clicking, I've had it from time to time. Assuming that everything else is fine (hubs&bearings good, tension fine), then it usually will get better after a few hundred miles.
