It becomes difficult to use a server as a firewall unless you have an 
"inside" and an "outside" network.  Easiest is to simply add another 
network card, should that be possible on your server.  Another 
possibility is to use VLAN taggging and connect the server to a switch 
that understands VLANs.

Yes.  I'd start on the FreeBSD website and start reading things that 
look useful.  If you're thinking about using pf as your firewall, which 
I'd personally recommend though other options are perfectly workable 
also, there's a nice document on the OpenBSD web site, IIRC.
