You don't need the other stuff until you get to around 100,000 miles.
100K mls is the extended service period on the diff oil and coolant, just like the 15K mls on the engine oil. Diffs and water pumps have failed before reaching that mileage. If you're looking for a more reasonable service period, then 60K mls.
