Congratulations! you've made a wonderful choice 8-)

oh? for almost a year now I have an AMD64 system and I've used reiserfs for 
all my filesystems without any problems! so I can really recommend reiserfs 
but I can't say anything about other filesystems...

I don't know about firewire and preemtion since I don't have firewire. But 
recent kernels have two preemt options: full and voluntary preemtion maybe 
you can try both and see what happens.

yup, if you want to use Flash then you need a 32-bit browser. 
to use win32 codecs you need a 32-bit mplayer.

never tried to use lilo on AMD64, since I switched from lilo to grub and never 
want to go back.

a little tiny: your /usr gets very big when you have a lot of programs (Gentoo 
installs everything on /usr by default) and your posrtage cache easily 
reaches ~3GB...

I suggest to create a /usr partition of ~8GB and a / of ~2GB

in Gentoo /usr/local is almost not used: du /usr/local only lists empty dirs. 
so this can just reside on the /usr partition

not that I know of, so have fun with your new system!
