Comments for this thread have been helpfu. I have done a test install from the live install cd. For now, I guess, 74 GB is enough for the entire system, leaving out my older /home directories and archives, so I just let the installer pick a preferred partitioning configuration. Next I think I'll try LVM for some partitions.
During the installation, the installer quit at the 50% point, right after installing the optional packages, and would not restart. This had thrown me off during previous attempts. As it turned out, it was simply necessary to copy the boot information from /boot/grub/grub.conf over to Ubuntu's existing grub/menu.lst. So far, so good. Thank you.
