I like the online help for Excel 2007 and want to leverage it for my
own documentation. However, it is too much information for my user
audience. Is there a way I can get access to the CHM files so I can
modify it for my own use?

Not legally. The chm files are subject to Microsoft copyrights, and
they have a LONG history of not allowing anyone else to modify their
copyrighted materials. I doubt your department could afford what it'd
need to pay to get Microsoft's permission to alter these files.
