As for page templates, they're used when creating a page and can include content also. You can create them by hand (see http://www.dnnstuff.com/Articles/tabi... for an example), but if you're doing that be careful that you make dotnetnuke aware of them (http://dnnuke.blogspot.com/2008/11/cr...). However, I find it much easier to simply use the UI i.e. create a page, add the content & modules I desire and then click the "current page" tab in the control panel and press the export button. This will allow you to name the template and decide if you want content or just the settings. Now when you go to add a page you'll see that template listed in the template dropdown.
