Shrinking disc Image to fit on DVD media

[mattb]

I am doing a project at Unnamed Wireless company, and I need to send out a updated Leopard image to 14 MacBook Pro's. this is a Apple that is used as a display device to show web surfing over EVDO. I need to know what is safe to delete or remove on the OS so I can possibly fit it to DVD dual layer media.
Unless you can split Mac image copies to multiple discs with the built in image software.
Any idea's?
