To save the packages and have them installed without downloading again..
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install dpkg-dev
sudo cp /var/cache/apt/archives/*.deb /<some_file>
sudo dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz
Burn <that_file> to cdrom as data.
At new installation,
sudo apt-cdrom add
Then install any wanted packages as recorded down by Avi's method.

ps: to keep conf files, put back any saved conf files in the relevent
