Good luck.

very simply, you access the Kindle devices "Settings" page and in the section that says register/deregister, you would click on the deregister option, once the device is online with the built-in wireless network connection. After which, the device is ready to be registered to a new account.
Please be aware that just changing the devices account registration does NOT delete any content; also changing registration does not provide the new owner the legal access to the books already downloaded to your Kindle, the original account that purchased the books, will retain ownership.
There is no way to give your purchased book library to the new owner of your old Kindle. If the new owner likes the books, then they will have to buy them on their own, to retain future downloading rights.

To register your new kindle you need to go to http://www.amazon.com/s?ie=UTF8&page=1&rh=i%3Aaps%2Ck%3Akindle%20registration and follow the directions.
