Facebook Intergration

I had a script coded for me that is an exact clone of [login to view URL] minus the webcam chatting. I need someone to edit it and make it so before you click chat that you have to login with your facebook. Then i want to replace the "you" and "Stranger" on the inside of the script with the users facebook names. And i also want there profile pictures on the left of there name, and i want the picture to link to there profile. The script is coded in clean php and ajax so if your fluent in both and facebook integration this should be quick.
