Sounds like a good plan to me.

Yes, this will happen, but not in the way you've shown: ad0s3a is the
first partition (a) on the 3rd slice (s3) of the primary master disk
(ad0). ad1s3a is on the primary slave drive (ad1). What you should
probably see is the current partitions are
ad0s1a, ad0s1b, etc.
And when you swap your FreeBSD and Windows slices, that should change
ad0s2a, ad0s2b, etc.
I recommend that when you copy the partitions, edit the /etc/fstab
file and put in the new device names before you copy. Preferably
restore the original fstab, and test that you can reboot using the new
slices before you install WinME over the original FreeBSD slice.

Shouldn't be any problems given what you say about sizing everything
above. Instead of using sysinstall, you might consider using the
basic fdisk, disklabel and newfs commands -- they're more powerful and
flexible than sysinstall but not so easy to use.

As far as I know, all of the Unix "ghost" programs are essentially
scripts build around dump and restore.
