I'd also leave the world file alone, and emerge -C the packages I want 
removed.

KDE3 is no longer in the portage tree, it's in the kde-sunset overlay.

World updates do not remove things, you need to use emerge --depclean for 
this. It will probably want to remove a lot when you never depcleaned 
before, so be sure to check. Put the stuff you want to keep in your world 
file with emerge -n, then depclean the rest. I guess it will remove your 
whole KDE3 that is no longer in portage. If you like to keep it, add the 
kde-sunset overlay with laymanl, and maybe emerge kde-base/kde-meta:3.5.

The KDE4 version is in the kde overlay, but I do not know if it is usable 
already.
