To (un)install software under linux using the suse tools:
Start YaST2 (type yast or yast2, no capitals).
With this tool you can add/delete components, check/change settings, backup/reinstall etc etc.
When installing software, you don't need to be concerned about the cd's, yast will ask a specific cd if needed.
Yast will try to check if certain programs conflict with others or if programs need others (dependicies). Yast will ask you if it cannot self decide what choice to make.
