Well, if you only need to use it as an ssh server, common sense would dictate that configuring your firewall (you are using ipfilter, right?) to drop all packets except inbound TCP on port 22. Now, in real life, that may break a few things (DHCP, NFS, etc). Hiding from ping is easy--just disallow ICMP. Get thee to a doc on setting up basic firewalls!
