Well I've used WPA supplicant for a while and probably can help you get you started.
What version of Suse are you using? 9.3 or 10.0?
If you've got 10.0 WPA supplicant should be installed by default. If not, browse to your Software Manager and find it and install it. That should be the easy part. That way you dont have to mess with download, unzip, compile, blah blah blah.
Please let me know which version you have. If you've got 10.0, I can walk you through the GUI with it since it's built into the GUI now.
