First off how much do you know about tube based electronics? Before working on a TV it is best to replace capacitors and practice soldering, component identification and schematic tracing on a 5 tube am radio or two.

Assuming you do have tube radio knowledge: it looks like the main problem is vertical roll. That should clear up if you adjust the vertical hold control...if it doesn't and you can get it to roll slowly in either direction with the control then sync is not being coupled to the vertical osc, and the vertical integrator is probably bad. If it only rolls one way the frequency of the vertical osc is off likely from bad capacitors.
Also while many radios of that vintage still work fine on their original capacitors TVs stress those parts much more and when those capacitors inevitably fail they can take out other much harder to find parts. If you haven't replace the electrolytic and paper dielectric capacitors I strongly recommend you do so before using that set.
