One of the best Linux apps for burning CDs or DVDs is k3b.
The best advice I can give for setting up a p2p is to go to freshmeat.net and search for one; SuSE doesn't tend to include them in the distro IIRC but it does include some graphical front-ends. If nothing else, Freshmeat will tell you the names of the packages/executables you want to be interested in.
Using WINE depends on what you want to do with it. I recommend uninstalling the WINE that SuSE installs for you using
su -c 'rpm -e wine'
You can then install a more recent version from www.winehq.org
(SuSE doesn't tend to keep Wine up to date; there are frequent releases on winehq that give significant leaps forward. You're always best off with the most recent version.) Then follow the instructions there to set it up and get it working. In general, you can run
to run progname
.exe from the current directory.
