You are able to set the computer name in the winnt.sif file of your XP CD. Looks like this: [UserData] ProductKey=XXXX-XXXX-XXXX-XXXX-XXXX FullName="Jesus H. Christ" OrgName="Christianity" ComputerName=OMGWTFNULL As for IP's, i think newly installed computers get their IP's automatically by default, so if you have a server, you can set up DHCP, and just limit the scope to 20 ip numbers. That way when each of your clients boot, they get an IP number in order to which they boot.
