Question : How to ghost 40 desktops

Hi,
      I have never done this before so not sure how to start.
I need to help a school in setting up 40 desktops that they just purchased. They are all identical.
What I'm thinking of is to setup one and load all the software that they need on it then ghost the HD and copy it to the other ones. Will Norton ghost allows me to do this?
Also, what happens to Microsoft license keys? Will they all end up with the same key? so If I try to register them with Microsoft what will happen? Also, will I need to go and rename the computer name for each?
Sorry for all the questions but never done this before.
Thanks

I think don't worry about licenses for now.
Yes, you would have to rename each pc.

Or you can try Windows System builder for Windows xp
