Clean Sweep

Question

This question is from my friend, as you'll notice in my 'model' section, I don't own an iBook. Her iBook is the final rev, she bought it about two months before the Macbook came out. I don't know all the specs, but I know she's not running iLife 06 but her computer is fully updated otherwise. Also, I think she's running 1GB of RAM.
Her question:
"I'm wanting to know how I can clear out all my stored passwords and make my computer safe to be used by other people w/o doing a clean sweep on the whole thing.
I know I can set up users and stuff like that, but I don't want to do that and I have reasons that aren't worth sharing. I basically just want to clear out all sensitive info and I'm wondering if there's a way to do only that. Furthermore, I want to make sure I don't lose my Microsoft Office but I do want to de-authorize my purchased music on the iBook b/c I've transfered it to another computer and don't want anyone loading it on their iPod from my iBook."
Hope you all can help her...

To expand on roam's response a bit:
Go to Apple menu > System Preferences > Accounts
Click padlock and authenicate
Click plus sign under login options
Create new user by entering a name and password (I don't advise creating an account without a password as the system requires a password when installing certain system software and will not accept a blank password field).
Check box to Allow user to administer this computer.
Go to Apple menu and down to the last item and log out user...
Log as new user
Go to Apple menu > System Preferences > Accounts
Authenticate with new password
Select old user account in sidebar
Click the minus sign under login items.
When asked if you to completely delete, answer Yes.
You have now completely deleted the old user, preferences and data.
Click on Login Options
Check top box in main panel to Automatically login and toggle the menu to the current user.
Quit System Preferences.
Now anyone can log into the computer.
If this was not intended by your question, please post back and clarify.
Good luck.
