Auto Settings

I have 277 Dell Latitude Laptops with Win XP SP2 to configure.
What or rather how can I make settings easier to set on each laptop? (EI:
Scripts, Reg edits, ETC)

I want to do the following:

Set a specific wallpaper
Set classic mode (theme)
Bypass all the orriginal setup for windows media player (when you 1st log on
to an account you have to run all the settings.)
Set a new default printer
Display the "My computer, network, and My Docs" Icons on the desktop

I don't have AD nor am I allowed to set it up yet.
The profile is for the students and I cant creat a roaming profile because
it brings the longon process to a halt.

Any help would be much appreciated.

Thank you,
