Transmission fluid will last roughly 70,000-80,000 miles so anywhere in there.
Automatic transmission fluid should be changed according to the manufacturer's suggestions. Many manufacturers suggest having the fluid changed at every 100,000 miles.
You do not need to worry about that. Toyota uses stable transmission fluid that can last way pass 150K miles. Unless you have problems with the transmission, you do not need to worry about it.
At 50,000 miles maximum is my recommendation. Your owner's manual may have a different mileage listed.

Depends on the car. They vary. Look in the handbook.
