Just a quick glance tells me that you may have jumped on your horse and ridden madly off in ALL directions.
We see it all the time. "Gotta get the cart up!" "What tutorials?" "What override system?"

Don't mean to beat you down as this is common.

The classic template is designed to temporarily give a look to you site as a go-by for your development of your own custom (override) directory.

Look in the "Free Software Add Ons" for override and get the pdf of the override structure. Utilize the tutorials to tweak your custom files. Lastly, trust FireFox when building and use the firebug add-on to further tweak your stylesheet for desired results.
