Coursepress course overview page is not correct

If you look at the overview for my course at the following address:

There are 2 areas of concern.

1) I have not specified a video, but a blank box appears at the top of the page.

2) The course structure does not break the units down into individual modules.

I assume I have set this up incorrectly, but can't find out what i have done.

I have 2 other questions;

1) Is there a user guide that specifies things such a recommended video and image sizes and goes into more detail about setting up coursepress and integrating it with marketpress?

2) Is there a sample website I can look at to get some idea of the capabilities of this configuration. My homepage looks a little dull, but I am not sure whether I can jazz it up with the supplied theme.

Thank you,
