Does this motor assembly include a reduction gearbox?

Yes, it has a built-in reduction gearbox designed to maximize output torque while regulating speed.

What motor driver model is recommended for control?

It is compatible with standard motor driver modules such as the L298N, TB6612FNG, or generic stepper drivers depending on the exact coil wiring.

Can this motor be powered directly from an Arduino board?

No, motors draw significant current and should always be powered via an external battery pack or power supply, with only control signals coming from the microcontroller.
