What's the best way to wipe user info on OSX without doing a clean install of the OS

Question

Hello,
I am going to give my old imac to my nephew so I want to delete myself as an Administrator and user (ie, remove all traces of my personal info).  However I DO NOT want to delete all the installed applications I have installed over the years as they are useful to him.
Should I just set up a new admin and delete mine or are there other things I can/should do to 'clean out' myself from the system?  (preferences, etc.)
Thank you!

Will deleting my admin account delete all my saved passwords in the keychain? 
Yes
How about my old emails?  In addition to Mail, I used to use Thunderbird.  Are there any special places that I need to delete files from for those apps?
Yes old emails are gone. No special places for Thunderbird, emails are kept in the User account folder.
And finally, if he wants to keep my itunes music, can i just drag my itunes folder into his account prior to deleting my account?
This is a copyright violation in most cases unless the music is free of that or the license allows it.
You should deauthorize the iTunes account in the User accounts being deleted, copy protected iTMS content won't play on his account. iTMS music is not copy protected but there is a 5 machine/device limit.
You can transfer music and other files to his account through the Finder > Computer > Macintosh HD > Users > His account > Public > Dropbox that will change the user permissions on the files.
Any iTMS purchased content is digitally signed with your personal information embedded into the files themselves.
If your nephew goes and P2P's your files, you could be held liable for copyright infringement.
If the music files are cd rips, then there is a good chance they are not digitally signed, however Apple might have done something to the files in the background to assist the RIAA against piracy.
There is a 5 device limit to iTMS content, so technically since he's family you can control that and it's included in the iTMS content license, but that doesn't apply to cd rips.
He might not like your music anyway and then seek to share it to get more he does like. So it depends upon the skill level of your nephew if he will do that or not.
Set up his account on the machine, maintain dual accounts until it's all set up, then log into his and delete your account.
Copy protected apps with one machine licenses that "phone home" you will have to either delete or buy another license for the new machine if it's a Mac.
