kde updates

I suspect that i am merely stupid and that this is the reason i cannot figure out how to do an online update to the latest KDE release. It is my assumption that i need to provide a directory string at ftp.suse.com, but can't for the life of me figurre out what it is. Although i can find the files, yast2 can't, and i never seem to be able to download the right files in the right order to just run the rpm's myself. For the sake of my crumbling self-esteem, can someone please help me. bc
