Ok so you have been through your intial backlup options for your FaceBook profile (See: https://accxess.com/backup-facebook/) now you have to consider collecting the dat that doesn.'t get included in the backup such as your contact, address book and email address's.
Some parts are easy to do with small apps, some are more manual.
The Apps:
Backup Friends: http://apps.facebook.com/backup-friends/
You Friends: You can get a copy of your phonebook via the Friends section of your profile.
Or you can do this to get your complete address book!

The trick, as you can see in the video, is actually quite simple.
Go to address.yahoo.com and click the Facebook icon. A login dialog should pop-up, just sign-in with your Facebook credentials and within seconds, you entire Facebook address book will be available inside your Yahoo Mail Account. Once the import is done, click this link to download a CSV file with the email addresses of all your Facebook contacts to your desktop.
You can then import the CSV file into Gmail Contacts, LinkedIn, your phone address book or any of the social sites where you want to connect with your existing Facebook circle.
Note: If Yahoo! is unable to import your Facebook Address book, open your Facebook page and choose “Application Settings” under Account. Next remove the “Yahoo! Contact Importer” application from your Facebook profile and try the steps mentioned in the video again.
