To briefly answer your questions:

Z-DOS and PC-DOS V1 (Both really versions of MS-DOS V1) only handle 320K
floppies.

MS-DOS & PC-DOS (really a version of MS-DOS) V2 and up handle either 320K
or 360K floppies.  MS-DOS V2 for the Z-100 defaults to 320K unless you
"FORMAT /9" to format at 360K.   MS-DOS V3 for the Z-100 defaults to 360K
unless you "FORMAT /8" to format at 320K.

Note that Z-100s with Boot Monitor less that V2.5 will not boot from a
360K system disk, but you are okay.

What is the part number of your motherboard ?  85-xxxx-x, it can be seen
by removing the video board.  There are lots of RAM upgrade info floating
around.

"Gen", what's that (-:    Seriously, if you have a fancy card in the S-100
either you can load a device driver with CONFIG.SYS for it, run a TSR from
AUTOEXEC.BAT to deal with it, or just let the application program drive it
directly.

Heath Users Group (HUG) has monthly REMark magazines, and Z-100 Lifeline
is a VERY nice all Z-100 journal that is bi-monthly.

The Scottie Board thing (I have schematics if you like to wire wrap to
save yourself ~$200) is used with HUG's ZPC V2 software that does a nice
job of PC CGA emulation.   ZPC alone (HUG ~$40.00) without the hardware
support works a lot of the time.
