Install/upgrade question

I'm new to suse and have a couple of installation questions. First, if I install 10.1rc1 is upgrading to final likely to be clean or should I just wait for the final release? Second, can I generate a functional kde installation using only the first CD? I'd rather not burn 5CDs or d/l a dvd iso. (and does anyone know why kde3.2 wasn't included w/ the rc?) Is there a complete list of available rpms somewhere? TIA Paul
