Hi Klebnor. I am a Carrara content creator and I fight together with Ringo Monfort and Daz3D to create a basic template for installation, and this is the same that I use to post products here at Renderosity.
The real problem is that Carrara alone cant look at their folder and update the information. This is one thing that I have asked to development team for long time now, and I think will be a next step for Carrara (Hope to see this in C8.5)... and you are right, there are a need for more information about how to install Carrara packages. But the rule is that almost all folders that are added need to be assigned by hand in the Browser.
What I do to dont have to add folder again and again, is add the Scene folder (the entire folder to the Browser), and not one by one as we see in the default installation. I do the same for all others folders like Shaders, Objects.
I cant post a printscreen because I am rendering a new image and it will take about more 4 or 5 hours to finish...
