Your description of the freewheeling unit seems correct to me.
Number of bearings: What kinds of bearings? Ball and roller bearings only? Even so, there are a lot more than three. I think there are at least 5 in the MRGB alone. Then clutch actuator upper and lower bearing, tail rotor driveshaft damper, tail rotor gearbox, rotating swashplate, blade grips, tail rotor pitch control... etc. Plus the ones inside the engine.
