Sounds like you got it covered!

all i would say is be carefull of so-called getwell kits.
much better to make a list of all electrolytic caps,
and buy them seperatly - use 105' low-impedance types.

some kits use cheap 85' rubish caps, and dont include a full set.

DONT FORGET THE CAPS ON THE AUDIO-REGULATOR-II PCB!
