Hi SolarTrees,
The book does cover how the Template Override System works, its advantages, and how to create and make use of one.
However, the book only provides a very simple example of changing a particular CSS element to customize your store's look. The reason being to avoid going into details on code-specific (e.g. HTML, CSS) areas which are covered widely in other books or websites and instead allow the store owner to concentrate on setting up and running a functional store confidently.
The book is currently on sale only at Lulu's site on this page. To have an idea of what the book covers, please click the "Preview this book" hyperlink on that page. Read the reviews (both good and bad) on that page as it will give you a better idea of whether the book will meet your needs.
One last word though - use the Overrides as Kim mentioned.
