just a cleanup-related question but on a debian lenny server that i've

that i can delete. i recall there's a utility that will identify unused
libraries but i'm curious about what else i can pinpoint that can be
removed.

this system is a web/mail server and, since its IP address is
assigned statically and another system is responsible for all DNS/DHCP
functionality internally, i conclude that i can remove the dhcp-related
packages. that's just one example.

Not that fast :-)

You may have installed packages that are "unused" but "needed" as a
dependency requirement of another packages that you want to keep.

If you are not facing space problems, I won't touch anything. What you
could do instead is disabling services you are not using at all, that's
what I use to do.
