If you want to exclude certain packages from the update, there is the /etc/urpmi/skip.list file. Either put the exact package names between the slashes or use regular expressions, to exclude a bunch of packages.
Ran remove-unused-packages as root (as you suggested), and then urpme --auto-orphans, and voila, the packages were no longer offered. Excellent. Solved!
