I think that the 'warped mouse' syndrome is caused by the wearing of the front support feet. A quick glance at my Lisa showed that I have about 1.5mm of feet at the front of my mouse, which is well-used but still quite serviceable. I am not encountering the rocking problem that you described, so I can only assume that your mouse is a little more used than mine. Fret not, as you can usually pick up Lisa/XL mice for around US$10 on the various auction sites.
As for the CRT problem, it sounds like the raster is off and the yoke needs repositioning (something that can occur as a result of being bumped, like during shipping). If you attempt to adjust the yoke, PLEASE BE CAREFUL! You could die or get seriously injured if the high voltage discharges through you. Of course, you have to adjust it while the unit is energized to find the right spot for the rotation of the yoke. Once you find that prefect spot, tighten the yoke down. You may have to re-adjust the yoke a few times as it can slip out of alignment while tightening down. A fairly easy procedure, but VERY DANGEROUS!! Please be careful.
Hope this helps,
Chuck

PS - did I mention that you need to be careful? ;)
