Research for Florence

So I figured out how to customize Google Maps... (I know, I know... I should've known...)
Here is a first try for tour spots in Florence, or I should say Firenze...
Grace's Firenze map

I didn't get a guide book yet so these are just quick searches of points, including from the New York Times 36 hrs in Florence article. If anyone has any recommendations, please let us know!! And Nadeen and Victoria, please add the points that you are interested in!!
