Facebook Connect Login/Register

Basically I need a proper working facebook connect script written. It needs to work exactly how ([login to view URL], [login to view URL]) works, including and only including these steps from those websites. FB Login button, prompts login, on call back ask for facebook premissions, Case 1: if first time login to site, prompt to register page for a few values user must add, Case 2: if returning user just send them to home page. If permissions for the site have already been granted, dont show allow permissions box again. Site must be in php and communicate with mysql db to track logins, points, etc. Site must contain a welceom <fb:name> <fb:profile-pic> eddit account, logout on top right hand side of page.
