Hi there,
Well, it depends on how long you've been gone! My suggestion would be to pick up a WDW travel book to get you familiarized.
As for fast passes, I'm not sure what you mean by one specifically for a family or why you might need something like that. When you go to the FP machines, you will get a FP ticket for each family member. The tickets will allow everyone in your party to go on the ride during the same time period.
