You can generally copy and paste configuration from existing switches to new ones. Hostname should be different, as well as interface descriptions if any are used. The IP addresses also need to be different.
In addition to what Kevin stated, make sure the new switch VTP mode is transparent until you get it situated on the network than switch to client. Also insure it's spanning tree priority is higher than the current spanning tree root on your network. That way it doesn't take over as the root.
