Books: French cooking began, at least for most American cooks, with Julia Child's Mastering the Art of French Cooking. Snag the 50th anniversary edition for $24 at your favorite bookstore. Find it at Amazon here. David Lebovitz's The Sweet Life in Paris (subtitled "Delicious Adventures in the World's Most Glorious and Perplexing City") is a great introduction to the food culture of the French capital. (There is a right and a wrong way to work your way around a cheese plate.) You can buy it new for $23 or used for as little as $5. (I often use the "buy used" option from Amazon's sellers and most of the books I've purchased arrive looking brand new.)
All of the Barefoot Contessa's cookbooks are wonderful and her Barefoot in Paris is one of those cookbooks that's as fun to look at as it is to read. It's just a beautiful book and the recipe for pear clafoutie is to die for. Available for under $20 in both print and ebook.
If you're frustrated that you can't order anything from Amazon France unless you're actually in France, check out French Books Online, a source for French language books in many genres as well as audiobooks, some of them bilingual. Authors in their policiers (crime thriller) section include Pierre Simenon (fils de Georges), Jean Amilia, Brigitte Auber, and Tonino Benacquista.
Chocolat is everybody's favorite French movie starring Johnny Depp. Buy the novel by Joanne Harris it's based on.

Paris Je T'Aime is a cinematic love letter to the city, and stocking stuffer priced at under $8.
