If the routers are already set up you can probably just plug into one of the LAN ports, grab a DHCP address, ssh/telnet in, and start scratching your head at the commands. Hopefully they have a web interface and/or the SSH service is enabled. I haven't done ios in a while but I can give you a couple of pointers.

'show run' shows the running config. It reads like a script, just a list of text commands, though some are grouped. typically you can just type in something from the config into another router.

'no' (command) removes one of the configurations. for example if ip proxy-arp is enabled then 'no ip proxy-arp' will remove it

I'm assuming you're just going to be changing ip addresses, so assuming the wan connection is on gigabitethernet0

terminal length 0
(removes linefeeds)
sh run
(displays the entire running config. copy/paste this into a text file so you can put it back the way it was when you break something)
config t
(puts you in configuration mode)
interface ge0
(puts you in the section for the interface you want to work on)
no ip-address
(removes the old IP)
ip-address x.x.x.x
(inserts the new IP)
exit
(takes you out of the interafce section and back to the main config)
exit
(takes you out of config mode)
wr mem
(writes the running config to the startup config, otherwise your changes will be lost on reboot)
reload in 0
(reboots the router)
