Gnome to KDE Woes

I bought a thinkpad with SuSE Enterprise Desktop 10. So far I’m enjoying it. But I found gnome to be a little plain, so I wanted to try out the KDE desktop. Well I installed the desktop, but some of the more specific functions did not migrate. The touchpad control application and the drivers that control volume and such are not there (or being recognized). How can I activate or put these programs into place for KDE? I’m brand new to linux, so please be kind to a n00b.
