Ok, so i'll summarize what i've read so far:
EFI/Fuel Induction Cleaning - Not necessary since I rotate gas stations (get the benefits of all the different additives that the different oil companies use) and since I am not experiencing poor gas mileage.
Alignment - Not necessary since I am not experiencing any uneven tread wear or pull from side to side.
Differential Service - Pseudo-necessary since I bought the car with 40k miles and don't really know the service history. I'll look into DIY'ing this one.
Power Steering Fluid Flush - this seems to be the controversial one. Based on discussions here and on
this website, I will look into this in more detail. Per the toyota parts and service website, I do not see a manufacturer recommended interval for power steering fluid flush at any point up to 120k miles (as far as that website goes).
Transmission Fluid Flush - Not necessary since I do not tow or drive under heavy load conditions per the toyota parts and service website. I may change this in the future anyway, I'll probably look into DIY'ing it.
I really appreciate everyone's responses!
