Do any of you clean cases with  the walnut treated with rouge the purple stuff ? If so do you swab out the very fine coating on inside of the case.

Maybe not...over the course of 100s of shots.  Several yrs ago, that "fire-lapping" kit consisting of abrasives & steel plates with which to impregnate a lead bullet was getting a lot of attention in gun mags, though I haven't heard of it a long while.  Think pre-impregnated bullets were also available.

Bullets for 'fire lapping' are still available. Every reputable barrel maker I'm aware of these days states unambiguously that using any of these in their barrel voids the warranty. They may be helpful in an old barrel with rust and pitting, but would never use in a newer barrel. If it won't shoot, I would be talking to the mfgr. 

Get a can of compressed air and blow out each case and wipe the outside. That's one reason I've gone to wet tumbling. Always made me uncomfortable to have that 'dust' in/on the case.

Any of those fine grinding polishing abrasives can be harmfull if inhaled.  most are based on some form very fine dust-like silicon dioxide (glass) crystals. 
In the lungs they create a medical condition Silicosis which has killed off generations of metal finishers, stone workers and any number of related trades.  "Black Lung" from coal dust is a somewhat similar disease. As I recall at times Silicosis was called "white lung" by stone cutters and quarrymen
In industry now OSHA requires workers who risk exposure to wear very special dust filter masks or even positive pressure hoods and suits.
I doubt that our personal reloading exposure to a little bit of jewelers rouge in the polishing medium will have that drastic effect but once ANY gets in the lungs it stays there permanently.   
That residual glass dust probably melts in the heat-pressure of combustion in the cartridge and along with glass particles from the primer could be part of the fouling in your bore.  It could possibly be a contributor to bore wear.   
If t'were me I'd clean it, probably by washing rather than blowing it into the shop air---sure don't want to dilute all those good lead particles from my bullet casting
