There are some package to control multiple machine install. Look up
recent post on this matter through google :-)
Here is an mature view.
I use "squid" for caching only ones downloaded. Another approach is NSF
mount /var/apt/cache and share its content between machine.
Making tar image and copy to another achine is another trick.

Instead of running full mirror, properly configured squid proxy may
require smaller foot print since it store only recently used ones.

how about doing "dpkg --get-selections > file.new" again. Then use sort and
uniq to create remove list. Then "dpkg --remove `cat removelist`" or
something should work.
To move files, ftp, scp, nfs, floppy...?

No.
