I'm thinking you need those things also... depending on where youre ordering your gears, you can always return the extra parts if you dont need them, that is, if you dont get a difinitive answer here before you go to work.
Hyper is right, order the complete kit from someplace like Drive Train Direct, it comes with everything you need except for the pinion depth tool which you'll need to borrow from someone unless you have a friend that works at a Ford dealer, good luck.
P.S. Try to get a kit with Ford Motorsport gears or US gear, the others are a bit loud.
