Create a couple of simple text files with nothing but the names of
the various packages you want per catergory then...
# cat av
xmix
xmms
xmovie
# apt-get install $(< av)
Reading Package Lists... Done
Building Dependency Tree... Done
Sorry, xmix is already the newest version.
Sorry, xmms is already the newest version.
Sorry, xmovie is already the newest version.
0 packages upgraded, 0 newly installed, 0 to remove and 182 not upgraded.

Don't worry, 99.9% of the time apt-get will do for you, and inform
you, of the "right thing" to do.
If I understand your questions correctly then these are all stock
standard Debian issues and not Knoppix specific.
