IMO you're barking up the wrong tree. Try a WP forum.

That said, if all else fails, try the following:
1) Download a WP template with the same structure
2) Download image files from the guy's WP template (use right click to save image as...)
3) Replace the image files in the WP template you downloaded with the guy's image files

I've never tried that but I don't see why it wouldn't work with a few minor changes to the CSS.
