2007 Toyota Tundra CrewMax 4x4 5.7l Maintenance Specs questions

Looking into some maintenance on my Tundra, now that it has 140k miles.
I just had the Transmission Flushed by the dealership($260).

I would like to change the other following fluids:
Front Differential Fluid
Rear Differential Fluid
Transfer Case
Brake Fluid
Power Steering Fluid

I need to know the type of fluid to use(Toyota-brand, Viscosity, System Capacity).
I am mainly creating this because I need to know the best brake fluid type to use and the quantity of brake fluid I need to buy to refill properly.
I cannot find any info on the type or quantity of power steering fluid either.

Also I have been lubricating my front and rear driveshaft's grease zerks every 5k miles as the manual states. However I am wanting to verify that there are only 5 grease zerks. I have read that there are 7, but I can only locate 5.

 

The differential change came to my thoughts just today. Watching for the responses. If any, I will get the juice from dealer, or equivalent, and make the change myself.
