I've never actually done this exact thing under these exact
circumstances; so I'm going from memory,
but here's what I'm thinking.
Ideally you want to boot from a rescue CD that runs the same
kernel release as a kernel installed on your hard drive, so that
modules for your running kernel can be found in /lib/modules/
after the switch from the initial RAM file system as / to
the permanent root file system as /.
I'd try the Squeeze/Sid installer or the "daily build" installer
to try to get a kernel match. And you want to specify the root file system
as the same partition as what would normally be mounted as root.
Something like
Rescue root=...
If you can't get a kernel match, then run the installer in expert mode
up to the point where you partition disks, invoke a shell, mount the
normal root file system somewhere, then do a chroot to that place in the
file system. For example, if you mount it on /mnt, then do
chroot /mnt
to get a nested shell that treats the "normal" root file system as
the root partition. Then do your "apt-get install lilo" After
installation, check out /etc/lilo.conf and compare with the documentation
man lilo.conf
Once you've got your config file tuned up, issue the command
lilo
with no operands to rewrite the MBR.

Yes. However, I recommend that you purge them for the following reasons:
(1) It's broken anyway. That's why you're installing lilo, right?
(2) If a kernel upgrade subsequently occurs, the post-install scripts
might get confused as to what boot loader to run
(3) You can always install it again if you need to

Anybody else out there have any corrections or tips?
Did I overlook something?

I don't think that's the right approach. Instead, boot the installer
in Rescue mode, chroot to the installation, and do the boot loader
install from there. See the Debian Installer FAQ

You only half quoted me. I gave your procedure as an alternate procedure,
but you didn't quote that part. The procedure that I suggested
to try first is superior, in my opinion, because, if it works,
it allows him to boot his full production system (X and all). The rescue
CD essentially becomes a portable bootloader. The chroot procedure
can be used as well, but a rescue CD which runs the same exact
kernel that he has installed on his hard drive and which is booted
with "root=..." pointing to his permanent root file system essentially
becomes a portable boot loader, allowing him to boot his full
production system.
