That was part of the problem. Keychain wasn't picking up the password and it had no entry in Keychain Access, so after some Googling, I found (from the MacWorld forums) how to manually enter the info. It works for the most part, just needing to help to remember what network it should be apart of. Just click the network, enters in the password automatically and click OK.
In some way, yes the iBook does have a PRAM battery. It relies on a capacitor that holds the PRAM info, that is charged off the battery.
