Was looking for a handy chart rather than "two whole books." That said, for anyone interested, I found it very helpful to examine the tables in the SQL database to see where and how settings are stored. E.g.,

SELECT * FROM modules

SELECT * FROM portals

SELECT * FROM portalalias, etc, etc

It was also helpful to examine the "DotnetNuke.template" file, located in the "Portals\_default" directory.  This is an XML file that contains the parameters and settings used when a portal is created.  Very instructive.
