Passwords and user names.. Help please!

[The Red Menace]

I recently gave my wife my iBook. Before doing so I changed the master password that OSX prompts you forr when installing software, looking at keychain items ect. However, now the computer promts her for a password on every startup. How do I change this?

Also I would like to change the name of the computer from my name to my wife's. Is there a way to do this? Thanks.
