Great, thanks. I DL'd the book and will read through it (your second
link). The III operates somewhat differently than I expected. Sounds like
my first step is to get SOS on a floppy so I can test the III and make sure
there are no disk drive issues before proceeding to the CFFA. Based on my
experience with the CFFA and the Apple II, I was thinking it was going to
be a bit more straightforward. Thanks for the info.

Unlike the II, which is relatively easy to configure to boot to any
(bootable) storage device in nearly any slot, the Apple III tries to
boot only from the internal floppy drive, and as Eric pointed out,
you'd have to roll your own ROM to change that behavior. The CFFA3000
works nicely in the III, but you lose the Drive ][ emulation
capability and you can't boot directly to it.
In the Apple III, everything is seen as a device and requires a driver
that SOS loads as it boots in order to be accessible to the system
during operation. You can't (easily) boot directly to the CFFA because
SOS requires a driver to be able to recognize it. Fortunately, SOS is
close enough to ProDOS that you can use the CFFA in an Apple II to
create floppies from the images you downloaded.
I'd suggest reading this PDF for more on how the III works:

It's the Osborne McGraw Hill Guide To Your Apply III. Pay special
attention to Chapters 3 and 4.
LMK if you have any questions about all this.
