Hello,
Expo has identical effect on all systems or models. Higher value will make small movements near the center more gentle so you can control model more precisely. Value 20 - 30% is commonly used for Aileron, Elevator and Rudder.
Dual Rates will only decrease rotation speed, but using it is not recommended since same effect is achieved by adjusting Rotation Speed parameter. Changing Dual Rate in the radio will make control signal little less precise because available range is smaller, so when using FBL these days it is not the best way to slow down flip/roll rate.
