Facebook Login from webshop

We wish to use Facebook login both on the Hi Facebook Login Developer. New Facebook login project. Create account with FB text seen on Create account page - Retrives info from facebook and insert on create account page (Firstname, Lastname, email and any other data retrivable when getting basic access) . If customer already have registered email in mysql, then instead login user and show text "Ett användarkonto med samma e-postadress som du angav på Facebook fanns redan skapat. Du har därför automatiskt loggats in på Mina Sidor, Välkommen tillbaka!" FB Logo with text seen on Login page - Checks in mysql if email already exisit, if so login using FB (similar as on http://www.freelancer.com with Welcome xxx + image) or else create new account with short text. Upon Login first time the user accept that client can access basic info and on facebook users wall a message is automatically posted with some pre-written text In Admin Staff can see list of all customers. If customer logged in via FB = show a FB icon before customers name or else not What other feature or suggestions do you have ? Showing initiative will make us choose you instead of other developers! Good Luck
