Well, its kinda hard to explain. A hone goes inside your cylinder on a drill or drill press and spins around inside and creates a cross hatch pattern. It pretty much roughs it up so its not completely smooth "glazed". Its needed for the initial break in of your engine, it wears the rings enough to ensure a good seal.

If you have highspeed internet (or patience to wait thru dial up) this video will answer your questions, just one thing he doesnt show is make sure to use lubrication if you do this yourself.

yes

Unless you're sure you know what you're doing, a machine shop is pretty much the only option. Honing and boring go hand in hand.

What are the advantages/disadvantages between the dingleberry and stone hones?

I'm not a machinest, but my understanding is that a Flex-Hone® ("dingleberry" style) hone is intended for final finishing on an already honed cylinder--not for creating crosshatch on a freshly cut bore. Flex-Hones are best used for putting a plateau finish on new crosshatch or "degazing" (i.e. cleaning or restoring crosshatch in cylinders when installing new rings in an old bore).

I imagine it's possible to use a Flex-Hone to install crosshatch on a freshly cut bore. But I don't think the same precision and control is possible compared with a rigid stone hone.
