I just signed up and I've lived in the 5eme for one year. Here are my suggestions for where you'll be staying. First and foremost, print out a list of "what's in season" from this website for your home-cooking. One thing that we painfully learned is that here is Paris, you can't buy everything any time of the year like we do in the States. And do try any cheese in season (my favorite is the "Brin d'Amor" but it's only fresh in July and it loses it's flavor by late August). As far as "home"-cooking goes, for the everyday, non-"Bon Marche" ingredients, you'll save time by popping over to Place Maubert. There's a produce shop, a fish shop, a butchery, a cheese shop (changed hands to a "Meilleur d'Ouvreur" last summer and the staff has gotten friendlier since), a good charcuterie, a decent wine shop, and a good bakery (closed on Wednesdays). But if you are in town over a Sunday, pop over to Place Monge's market and get your produce from the far back left corner -- you can't miss the line. Most are open Tuesday through Sunday early afternoon. Around the corner is Eric Kayser if you want to try the best of authentic French baguettes (crispy crust, and oh so good interior). Their Lemon Meringue Tart is trés excellent also. The basement of the Monoprix in St. Germain across the street from Les Deux Magots and the Church is a good choice for cooking. They carry a better selection and quality of products then other Monoprix's in Paris. An off-the-beaten path recommendation for a restaurant near the Arc de Triomphe is Grain d'Orge at 15, Rue de l'Arc de Triomphe, 17eme (phone 01 47 54 00 28). It's listed in the Michelin Guide as a "Bib Gourmand" and every time we go there, we hear people speaking French and no one speaking English. They feature menus and foods based on beer (like beer mousse soup - trés trés bien and I don't like to drink beer) and their menus are about 30-40 euros if I remember right. And if you have any further questions, ask away!
