Yes, but you'll have inconsistencies if files change in the middle of
the copy.  For the most part it's not a big issue though.

I would boot the FC4 CD/DVD in rescue mode and use dd to make an image

dd if=/dev/hda of=/dev/hdc bs=65536

make sure you get your drive device identifiers right or you'll hose
your disk without warning.  This also assumes the 2nd drive is at least
as big as the first drive.

No, sw RAID is not really useful for offline backups.

You can share /home over the LAN using NFS, and that is quite common.
See the many how-tos on setting up NFS.

Almost definitely not possible for numerous reasons.

Hmm, may be possible, though shared library conflicts might be an issue.
Almost definitely not worth the hassle though as it will royally screw
up RPM in both FC and Mandrake if you share /usr.

Hard to do because of the mkinitrd boot image which will contain IDE
drivers to boot on your P3 but not your P4.  You could probably fudge it
to boot on both but this would be VERY advanced.  Plus, kudzu would go
mental each time the hardware changed.  Again, not worth the hassle.
