Question about hosting script files locally

Jul 14, 2010 at 7:38 PM gives clear step-by-step instructions for hosting jPoint and jParts locally for version 0.7, but they do not seem to apply to 0.8.  Am I wrong and just too dim to understand the directions?  Are there instructions for hosting 0.8 locally?  I am having trouble understanding exactly how to implement the example jParts on my site.

Also: my site uses Sharepoint 2003.  Is that a problem?
