Hi Ted,
To answer your first question, XOOPS comes with a standard set of modules with it's installation and does not have a feature to randomly and automatically create new modules for you.
You will need to visit the Module Repository on this website and download what you would like to use, unzip the folder and then upload the module's folder onto your server and then from there, install the module from your Module Administration Panel inside your XOOPS website.
As for the second question, I'm not sure. Hopefully someone will be able to answer that for you.
