Ok I need some help here

While doing an apt-get upgrade I got this message

What I want to know is, I am guessing that there are new packages available
that will upgrade my system to the newest debian/KDE woody available.

So if I use apt-get dist-upgrade will this erase the 125 packages,
and then reinstall all those packages automatically?

If not how do I get those packages back on my system to keep my system the way it is just upgraded?

Im just a little paranoid cause I dont want to screw up my system.

So if possible could someone just walk me through their experiences using
apt-get dist-upgrade?

Thank you in advance for your help.
