I know I have mentioned this before, but the absolute best maps for driving in any part of Italy are those published by Touring Club Italiano. They have them at every level from the entire country to individual cities. Particularly scenic drives are marked, and I think even the minor dirt roads are on those maps.

I know they can be ordered from The Savvy Traveller in Chicago (http://www.thesavvytraveller.com) I have no interest in the store other than to make purchases there. I am sure there are other places you could find the maps.

Have a great trip!
