Usualy what I do I create one config file per host that I'm adding and organise them in folders by type of host. So if I want to remove a host I just remove the config file.
Ex: Printers, Routers, switchs, etc...
It depends what type of host you want to add, as you will not use the same client or protocol to add a windows machine or a router for example.
For a windows machine you will need to install the NSClient++, for a Linux/Unix machine the NRPE client and for printers/routers and many other network devices you will most likely use the SNMP protocol.
Just let me know if you need more help on the subject.
