Use a Debian netinst CD - 118MB or so. That installs a base system
and you can then reboot. It's about six questions or so using the 
"expert" install - and that includes setting up users.

You mean

"dpkg --get-selections >> myselectionsfile" from one box and 

"dpkg --set-selections < myselectionsfile" on the other?

This works even where the machines are different architectures - I was 
able to do this where one was an AMD64 and one was a Sparc with minimal 
changes.

[There is also an equivalent which will preseed the debconf answers
but I can't remember that off the top of my head]

If you want a full system once you're done including X Windows and 
CD/DVD burning and the ability to add modules for firmware etc.

"aptitude install kde xserver-xorg kdm k3b build-essential 
module-assistant"

Disclaimer: I can claim to have _named_ apt :)
