That's probably over kill. Mostly you'll be pretty safe if you stick to trusted
web sites and use iptables to block inbound connections. There may be some
kernel bugs that could get exploited without an actual connection, but those
attacks will probably be rare and if your router is doing NAT very difficult
to send on to this machine.

As far as compromizing other machines, they should be set up to survive on
their own in any case. The main additional threat is sniffing local traffic.
Depending on what kinds of local traffic you have, you might need to take
some steps to mitigate this threat. In general the risk of the old machine
being compromised if treated as above isn't going to be a lot higher than
that of other machines used to do more risky things.
