Dale, I tell You one thing - choose multilib. This don't do nothing wrong.
You can use 32-bit app compatibility and this don't reduce performance of
overall system. Easyest way for Me is:

- boot minimal CD
- format drive (partitioned allready)
- fetch with links stage3 od amd64
- fetch portage
- unpack
- mounting binded dev and mounting proc, copy resolv.conf
- chroot and update environment by env-update, source
- set environment (timezone, fstab, net)
- emerge some standard packages (vixie-cron, syslog-ng, dhcp, dbus, hal,
udev) and making global system update (-uva --deep system), setting USE
flags and CXXFLAGS as needed.
- emerge lilo, genkernel, gentoo-sources
- setting genkernel with menuconfig and run kernel compilation
- configure lilo ;) and running lilo.
- reboot
- emerging rest of software - aka KDE4 - this will push all packages needed
(aka. kde-meta will take deps like xorg, mesa and else so You don't have to
worry about - enable hal flag for convenience :) ).

Done! Works for me, without any incovenience, as You see nothing strange
happens, os is working without any strange things to do. You can set now KDE
profile, it should be listed by eselect for portage optimization.

One You should do: choose lilo - it's old, it's good, it's tested.
Configuration is fast and it's up and runnning in no time. Multilib you
should set for some applications compatibility if You will fetch in future
some deb/rpm packages from third party companies.

Be aware _lastest_ available in portage flash player - it has no support for
64bit browser (i don't know why). I've needed to get downgrade by hand. Now
after each upgrade flash player must be downgraded by hand (sic!) i will
mask it in packages.mask localy ;).

That's it - pure purity (64-bit only) can make you sick later, ill tell You
