The Aisin kit comes with (per the photograph) the belt, water pump, tensioner, tensioner pulley, and idler. For other parts you want to get I'd suggest getting them from Toyota (either a local dealer or one that sells online), including the coolant.
I wouldn't mess with the crank seal or any other seals (including the cam seals) unless they are leaking. They can be hard to remove and reinstall correctly. OEM Toyota seals are excellent quality and should last hundreds of thousands of miles.
