The template from the demo (i assume you mean sardless.com) is not available, but if you really wanted to use it you would have to look at the generated HTML code. The template on sardless.com is mostly HTML and only uses a few Simple Review tags.
You need to put them in a Joomla position such as left, right, banner, user3 etc. It really depends on your Joomla template as to where these will appear. The modules aren't designed to appear inside the component itself, they meant to appear in your Joomla template.
At the moment there are no user review and I still do not have an ETA, for me there are more important issues which need to be added to Simple Review such as 1.5 native compatibility.
