read through the file in the middle it will ask you whick session manager you would like to use uncomment and select your desired one. Scroll to the bottom uncomment #Gnome and put in kde-<version>. Where <version> is the version of kde that you installed.
control x then y to save then enter
at the prompt type
env-update
source /etc/profile
assuming you properly configured your X enviroment you can either reboot your system, and you should go to your session manager and kde automatically.
well before rebooting if you type X -config /etc/X11/xorg.conf this will test your X settings if all is well you should get black and white screen and a mouse curser. Press control alt backspace to exit and restart your computer.
If your X configuration was not setup correctly try typing xorgconfig and go through the prompts. When you are done save and reboot.
If you get any errors at all please post them here.
