You can't go online with SuSE. Why not? Bit of problem then. Otherwise I would've directed you to
http://linux01.gwdg.de/apt4rpm/ so you could configure your system to use apt. Just to show you how easy it is to upgrade your machine in one easy hit, all you would have to enter on the command line when you've got it configured would be:-
apt-get update
apt-get dist-upgrade
Alternatively, there is a couple of easy GUIs (synaptic or kynaptic) that will do the job.
If you are really stuck, go to the UK mirror site on
http://www.mirror.ac.uk and navigate to the suse mirror. The web interface has an option to download entire directory trees as a tar file.
Any graphical stuff you need (like splash screens etc.) go to
http://www.kde-look.org
Hope that helps.
