Is there a way to give an Ubuntu update repository a list of installed software on another computer, and thus download updates for another system to be transferred to that system via memory key or even CD/DVD?  I'll continue to have personal access to both PCs for maintenance.

 But, I'm fairly sure you can drop the .deb packages on a CD or
something and just copy them over, like this:
