What Should I See in Paris?

I've been reading Paris for Dummies (2005), but today checked out guides more up-to-date. They are Access Paris: The Only Guide That Leads You Street by Street into the Heart of the City, published in 2008; and Fodor's Paris 2009. Using these books, I'm drafting a schedule of what I want to see and when during my week in the City of Lights. What would be at the top of your list?

Paris: City of Lights

The DVD Paris: City of Lights, produced in 1995 by View Video, is not well shot or written, but even that could not quell my growing excitement about visiting Paris. In one hour of viewing I was reminded of Paris' history, and the great men and women whose lives have contributed to her fame. I thought of beginning a list of those who have contributed to Paris' fame, or those French names that have become recognized world-wide, but I soon realized how huge it would be. I think of Berlioz, Debussy, Delacroix, Voltaire, Hugo, Braille, Nadar, Manet, Monet, Matisse, Degas, Pissarro, Renoir, Seurat, Valadon, Marie Curie, and on. When you think of French people of note, whom do you think of and why?

By the way, I discovered a "List of French People," organized alphabetically by profession, on Wikipedia.
