Firewalling is optional, but from what I hear if the server is to be a 
Windows box, that would be a good start...

Apache can do virtual hosting.  Its easy to set up domain names cheap as
$10/year with any number of DNS hosting services with simple web based
forms.  Only one IP address is required...

Mail is going to require its own IP address for each host.  There doesn't
seem to be anything in the RFC's yet to share names.  A way around this is
to use use procmail to seperate the accounts to all those different mail
addresses on that same server.

Ftp, and the rest I haven't tried yet.
