How fast of a connection are your firewalling?
At home I've got 608K DSL (unusual number, 608) and using a Compaq 486/33
underclocked to /25, I run around 15% utilization when I iptables
masquerade at full line rate. That's using two 16 bit ISA ethernet cards.
This may help you estimate how fast of a connection you can handle.

In addition to plain ole iptables masquerade, I'd personally install squid,
ntp, and bind. You may as well use squid to get some benefit out of the 8
gig hard drive. "Obviously" you want to dpkg --purge telnetd, etc.
