We're sorry the instructions are outdated. We'll look into updating them with recent Facebook changes. Unfortunately, they change their developer area on a seemingly weekly basis, which makes it impossible to always be up-to-date.
As for the fields to submit, first, you need to enable a Social Profile plugin and configure the Profiles area of JFBConnect with the fields you want to import. Once that's done, after you've performed a few test logins using your administrator Facebook Login, the submissions area will show you which permissions you've requested. You only need to submit for review those permissions.
If you aren't using a Social Profile plugin, you don't need to submit any fields for review as all JFBConnect would need are the basic settings.
I hope that helps explain,
Alex
