I haven't looked in a while but I'm pretty sure that Books Online have a pretty good overview and some pretty solid configuration steps. Additionally, it would be good to search this site or google for configuring SQL Server 2000 replication.
Post again if you have some specific questions after you get some research done. Thanks.
