is there ever a point in the process of using carnauba - based waxes where you would do something to remove the previous layers of wax? IOW, when using HD Cleanse, is it applied right over a waxed surface?
HD-Cleanse removes whatever wax is on the surface.

What should be done when new swirls appear in a properly prepared and waxed finish? Do the swirl-remover products work over the wax, or must the wax be removed?
Swirl marks are actually very light scratches in the finish. There are different kinds of swirl marks. Some swirl marks are caused by the improper use of an orbital buffer; if you've ever seen a car whose finish looks like it has patches of concentric circles in the finish, that's the cause. The swirl marks term can also refer to scratches in the finish in various directions that reflect sunlight.
Regardless of cause, the removal of swirl marks requires the use of a product which is also strong enough to remove the wax. A mild cleanser like HD-Cleanse as well as a stronger, slightly abrasive swirl remover product like the Meguiars or 3M swirl remover, will each remove any wax on the finish.

What about you guys who are using products like the Griot's Machine-applied polishes. Do you have to remove previous layers of wax before proceeding with the machine buffing?
There's no difference in concept between machine-applied products and hand-applied products. An abrasive polish like the swirl removers will remove wax, regardless of whether it's applied by machine or by hand.

What would a pro detailer do-would they take the time to wash the car and remove all the wax, or do their machines/products cut right through?
A professional detailer would go through the same steps as an amateur - claying to remove any surface impurities, cleansing to remove oxidation, swirl removing as needed, followed by a coat of wax.
An experienced professional sometimes uses tricks and techniques for various problems that might be present. They often use buffers to speed the process. (Buffers can be a time saver, but improperly used they can also
cause problems on the finish.)
The do-it-yourself detailer can use many of the same techniques and can buy the same equipment as the pros. There are a few books on the market that have a lot of information on detailing; for example, at
Classic Motorbooks, you can buy "Auto Detailing: The Professional Way" by J. Joseph ($23.95), or "Automotive Detailing" by Don Taylor ($17.95).
There are advantages to using a good professional detailer. If he's good, he has the experience to know exactly what's best for your car. And, of course, it saves you time. The downside is primarily cost.
