You have at least four options.  The first is to just install it as a
normal x86 (using basically the same settings you probably use now, since
I see you are on AthlonXP, only with SMP for the dual-core, and perhaps
-march=k8 in your CFLAGS).

The second is to go 64-bit multilib, the default, which makes most stuff
64-bit, then merge mplayer-bin, firefox-bin, etc, as precompiled 32-bit
binaries, if desired.

The third option would be 64-bit with multilib, but also do a 32-bit
chroot.  As you already have a 32-bit machine, you could even use its
packages (if you have FEATURES=buildpkg set, or using quickpkg to create
the binpkgs and just copy them over, or just image the entire thing and
copy the image as is.  For this option, you'll want to read the 32-bit
chroot guide at:
http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=2

The fourth option is a 64-bit kernel with a 32-bit userland.  I'm not
that familiar with this option, but see the amd64/2006.0/32bit-userland
subprofile.

In any case except possibly the first one (and possibly even there for
simple information reasons), you'll want to read the amd64-FAQ at:
http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml.  All the above options
should give you working win32-codecs as all will allow 32-bit versions of
whatever you would be merging to use those codecs.
