Hi,
the problem you have, is that you used latest kde/gnome builds for sid instead of "backports" for woody, try out the following:
if you search for "kde" on apt-get.org then you get this result:
Karolinas KDE 3.1 packages for debian (Added 2002-11-28, last checked 2003-06-24) (Download as text)
just put the URLs your sources.list:
deb
http://wh9.tu-dresden.de/kde3/karolina ./
deb-src
http://wh9.tu-dresden.de/kde3/karolina ./
(deb-src isn't needed if you don't want to build the packages by your own...)
after adding these lines to your sources.list just run an
apt-get update
and the packages should be known to your system, now you can install kde 3.1
same for gnome
Gnome2.2 backport for Debian woody. Also includes evolution 1.2.2, mozilla 1.2.1, gnucash 1.8.1 and galeon 1.2.7 among other things.

hope it worked
