Some of your questions are answered here, right on the top (I hope I
link to the up-to-date version and not the outdated one):

http://www.gentoo.org/proj/en/desktop/kde/kde4-guide.xml
http://www.gentoo.org/proj/en/desktop/kde/

I don't know if my advice beyond those links is of any use as I did it
all the "wrong" way -- didn't unmerge previous kde, just unmasked the
new kde versions, didn't use sets, still have USE="-kdeprefix" etc.
Still, sky didn't fall on me, at least not until I unmasked the
then-unstable xorg 1.5 ...
