Good spoke wrench first.
Some means for measuring tension next. If you're musical and have a good ear and a known good wheel that's the same size and laced the same way with the same gauge spokes matching pitch works. I've tried it but my ears aren't that good. I use the Park Tensiometer.
Then an actual truing stand.
And last but not least, enough beer to last through the evening.
