Whatever grease you use, do so SPARINGLY! The front sleeve needs only a very thin film of lube. Very THIN film. The needle roller bearing in the rear pulley needs a thin layer of grease periodically. There will be some grease that escapes past its little separate seal. That needs to be cleaned off periodically, too.

The philosophy is: no grease gets on the belt or pulley faces. Ever.

I don't know a thing about the "racing grease" in the photo but I am sure it would be fine if it is sticky and not runny.

Too much grease will get on the belt, transfer some to the pulley faces and make the belt slip.

Slow acceleration, high revs at low speed, revs don't increase smoothly with speed, increased belt wear.

The grease on the drive pulley axle should be so thin you can't see it.

You may get by with a good cleaning of belt and pulley faces if you don't delay. And removing excess grease at the same time.

No, you want to pack the rear sleeve with grease. It does leak out during the life of the clutch, but not where the belt can touch it. Most rear pulley failures are caused by this idea that just a little dab'll do ya on the needle bearings. If you've ever looked at a Honda factory service manual, they will show you that the fourth hole in the rear plate, that doesn't take a pin, is for filling the part with grease. Use way more than you think you should, then block the end of the outer bearing with your finger when you press the clutch onto the shaft.
