I would suggest replacing the Transmission fluid, differential oil, transfer case oil, brake fluid, and engine coolant at Toyota's recommended intervals. These intervals do not all agree with what you have listed by the way.
I normally do not balance the tires or check alignment, unless I detect a problem like the car pulling to one side. I do rotate the tires twice a year when I put on/off my winter tires. If you don't see a difference in tread depth between front and rear tires, then I wouldn't even bother with it.
The thermostat and water pump do not require scheduled replacement. Change them when they develop a problem.
Get a tuneup at Toyoto's recommended mileage.
Don't worry about the power steering fluid or the timing belt because your RAV4 doesn't have any.
Here is what someone else told me in another reputable forum.
5K balance tires. Nope, only needed if I notice a vibration at highway speeds.
10K check alignment. Nope, only needed if tires are wearing uneven, or vehicle is pulling to one side, also may be needed if vibration at highway speeds
30k transmission fluid. Do what your owner's manual says. Most likely it will say something like "replace at 60K if towing, or if it changes color to brown from bright pink.
45K Rear Differential Oil, Transfer Case Oil, Power Steering Fluid. That is so laughable that they recommend changing these. As someone as already stated, those are in sealed units and no need to replace.
90k Tune Up Do this only if the vehicle is running rough. The days of doing a regular tune up have long past.
90k Timing Belt. Check your owner's manual. I have an 04 HL 4 cyl that does not have the belt, it has the chain, but your owner's manual will tell you if/when to do this
90k Thermostat. If the temp. of my vehicle is fine, why would I ever change this?
90k Water Pump Nope again, unless I had to change the timing belt as usually they have to remove the water pump anyway. You would also want to change the accessory belts during the timing belt change. Most dealers will have a "timing belt change special" where they will do the belt, water pump, and accessory belts all at once.
I also check all the fluids and tire pressure on my vehicles at least monthly.
