Gen 3 Toyota Tacoma TRD Off Road Maintenance

My Tacoma is about to hit 80,000 miles. I've been getting oil changes regularly every 5000-10000 miles. I have not done anything else and currently don't have any issues with the truck.
I really want to make my truck last as long as possible.

What are some regular maintenance that I need to do and when?
Transmission flush/when?
spark plugs/ when?
break fluid/ when?
differential flush/ when?
Transfer case oil?
Lube propeller shaft?

 

Check the manual. I was just looking through it for my truck. It spells out exactly what needs to done at different mile markers.

 

3.5 v-6 plugs at 60k
I would also replace the fluid in the front and rear differentials, transfer case and transmission fluid service. Air and cabin filters should of been at least replaced once if not twice by now!
