Just to be sure, /home will remain unaffected if you specifically tell
the installer to not affect it (which is rather easy, but the default
action is to clobber it).

dpkg --get-selections 

will get a list of those packages you have installed, so if you do

dpkg --get-selections > somefile

and then copy somefile to somewhere safe, once you've installed you can
put it back and do

dpkg --set-selections < somefile

and it'll set dpkg up to reinstall all of those packages onto the new
install once you do a 

apt-get update
apt-get -u dselect-upgrade
