I think I've got lateral trueing right - no trueing stand, I use cut off zipties attached to the frame forks as a reference. For radial trueing (and to do a better job), I'd need to actually get a trueing stand... in the meantime, I found that plucking the spokes like guitar strings helps me to avoid overtensioned spokes... too much tension sounds too high pitched when plucked compared to other spokes. I'm hoping that will avoid too much radial deformation. But I really should just get a trueing stand - I'd ask the bike shop guy to do it but it takes him three days!
