Yes, I did adjust vertical height & linearity before beginning purity & convergence. They were really good around the time I took the "after" photo with crosshatches. Then I decided to actually watch something, using a digital converter box.

My wife came in and said, "Hey, that looks great. Can I watch Boston Legal? Oh -- and can you get rid of those dumb white lines dancing back and forth at the very top?"

Who can resist showing off? I monkeyed with height & linearity to overscan so that the extra program material disappeared, and now they're a bit wrong, of course.

After that, I started over, doing purity & static convergence by the book. Not so good! Convergence is off everywhere, and I can't get back to the pure white center dot that I had before.

My son helped me by staring at the screen during part of this phase. He eventually got frustrated. "No, Dad -- that made the green dot sort of rotate or move diagonally instead of up. Isn't there a control that just says 'move green dot straight up'?"

"Everything affects everything" would be a good comment to add to all of these instructions. I noticed that some of the convergence adjustments had a slight effect on height/linearity, for instance.

I'll start over again, following the instructions closely. I know the TV can produce a decent picture, so the fault is mine, not the machine's. For example, here's a snapshot of Boston Legal after I overscanned the height and then started "doing everything right." Not perfect, but at this stage, I'd be happy to return to that configuration!
