How are the fish doing today? Btw, there's a newer method (hybrid TTM) that doesn't use copper and only uses hydrogen peroxide right before the transfer. Humblefish has the details on his site and the method seems pretty solid for those who want to self QT. I've never used copper in the past, but did lose a few fish from stupid mistakes (too much prazi), which is why I switched to general cure for wrasses. Now I just buy my fish from one source that fully QT's, it's not cheap, but I don't have the time or space to do it myself and it's worth the extra expense to have peace of mind.
I think you're approach is good, quality food, minimize stress and let them be.
