I am sorry, it's been a while since I looked at the data which came along with the theme.
If you go to the page that you want to adapt on the demo site and look at it through the Firebug browser add-on, you will be able to figure out the individual module/components that were used in creating it and the general layout by looking at the names of the div classes. It's the simplest way to quickly see the structure and recreate it in page builder.
I agree with you that live sites should never be worked on.
As Devin wrote above, its ideal to have a development environment set up synchronized with your live server whereby you push the live copy only after it's been tested in the development environment (even on your localhost desktop computer).
