Any recommendations for a good book/web site/videos to provide insight as to the best way to set up a site for easy maintenance/updates of the content? Possibly by multiple updaters? W/O ending up with a spaghetti fest?

New to DNN and not real comfortable with how it all "hangs together".  I like some of the effects of DNNGo modules I found, but don't have enough knowledge to determine what I need to do to make things work (e.g., xblog Dashboard looks nice - but wants a link to a data module - don't know what one is, or what would qualify to provide whatever dashboard needs, etc. - shows only 1 data module to connect to, but I can't figure out how to get data into the "News" module so that it connects to the "Effect09 Gallery View" and displays in the scroll, etc.)

So I need a better foundation in what's going on with the modules, how they interconnect, etc. - but don't really find that info on the DNN website (or the DNNGo website, which SHOULD doc this stuff for their own control...)
