Should be fairly straightforward once you have your base FC4 install done. Are you looking at configuring any kinda of authentication to control user's logging in and allow logging on a per user basis of sites visited? Also, are you looking at setting up any kind of filtering or blocking of sites through the Squid ACL's or SquidGuard? May I suggest you also look at
DansGuardian for more advanced content filtering, depending on your needs.
