I was considering changing these fluids:

Steering
Transmission
Differential

Does anyone either agree to go ahead and change these or does anyone advise against it? Any other fluids or other maintenance items I should be considering?

A shop I took my car to suggested I do these jobs in addition:

Drive Belt and replace steering gears for rack and pinion. However they wanted a lot of money for this job which seemed not necessary to me atm. I am not experiencing any steering issues.

Thanks so much in advance.
Steering, yes, if you feel they steering is mushy. If you do a simple flush is all you need.
Transmission fluid, yes, if you feel that the shifting feels a bit sluggish. If yes a simple flush is all you need.
Differential oil, no, not needed at all unless is an aftermarket clutch type.
Drive Belt (assuming you mean accessory belt) if it looks cracked and or frayed then replace it, if not just check it regularly.
