If you would like a list of packages that are currently installed you
can get it by typing this at a command prompt (terminal window):

$ dpkg --get-selections > ~/installed-packages.txt

If you are using apt's dist-upgrade method to go from hoary to breezy,
it will automatically update every package you have installed to the
latest versions.

If you would like to do this via synaptic you can edit your
repositories using the Settings menu and selecting Repositories.

In here, you can change each instance of 'hoary' to 'breezy'.  After
you have done this, clicking 'reload' will get all the information for
breezy.  You can then Mark All Upgrades, and hit apply.

More detail, and other methods are listed here:

I'd say good luck, but it'll work ;) So, have fun!
