Yes, pack the bearings with grease to hopefully hold your oil in from just running out of the hub. Grease on the planetary gears makes the hub growl when the gears are engaged. Just oil on the planetary gears seems like it would run dry quicker, so I've been greasing the sides of the gears and shaft....and maybe a little gets in the ring gear too, but I coat all of that with gear oil. Coat all of the internals with gear oil and put a light coat of grease on the brake shoe ramps. Once everything I want greased is greased, I'll assemble one half of the hub and add more oil so that everything is rotating in an oil bath. Just don't fill it excessively to overflow past the bearings.
The NOS red band discs I've had came in the wax paper bag packed with grease. I'd be tempted on my next rebuild to use oil like in a New Departure for the discs too.
The main thing you want to avoid is putting grease on the internal parts too heavy and letting the hub sit to dry out. Grease on the index spring can cause it to stick to the driver and not do it's "ratcheting" job. Very light grease on the driver threads is ok, but once that cakes up, you get actuating issues.
