Skins,
I put this list together for a friend a few months ago that was going to mardi-gras. I'm not going to go back and re-link everything, but you should be able to copy pasta. DISCLAIMER: I am not sure how the oil spill may have affected the food at some of these places, so ask questions.
Here are some of my fave restaurants and other fun spots in NOLA. I tried to divide things by category and neighborhood.
Central Business District (Downtown):
Mother's: Great poboy (sandwich) shop on Poydras. Walking distance from the Marriott. Great for lunch. Get the Ralph and some File Gumbo. Casual. Lines to eat sometimes but they move fast.

Drago's: Famous Metarie oyster house that opened up a location in the Downtown Hilton. Chargrilled Oysters are to die for. Stuffed Lobsters are amazing. Casual and not that expensive.

French Quarter:
Cafe du Monde: A must. The french coffee (cafe au lait) and biegnets here are amazing, even if its a bit touristy.

Acme Oyster House. Near the corner of Bourbon and Iberville just inside the quarter. Great for Louisiana classics and fresh shucked Oysters on the half shell.

K. Pauls: This is famous Chef Paul Prudhomme's outpost in the Quarter. A little more expensive, but still a casual seafood spot. Great fish, gumbo and Louisiana classics.

Mike Anderson's Seafood. Great fish and seafood in the quarter. Their Crawfish Bisque might be one of my favorite things ever. The Norman is outstanding also. On Bourbon Street. Somewhat pricey but casual.

Arnauds: Another great, more upscale seafood spot in the Quarter on Bienville. The bar there, French 75 was recently named one of the best bars in the country, and serves classic New Orleans french cocktails. They have a live jazz brunch on Sundays.

Fine Dining:
Galatoires: maybe my favorite place in NOLA. Open since 1905. On bourbon in the quarter. Jackets are required for men at dinner. Excellent food. Fairly pricey.

Commander's Palace: Another NOLA standard. In Uptown on Washington. This is where Emeril and Kevin Rathbun learned to cook. Expensive. Jackets for dinner.

Cochon: This is in the Warehouse district on Tchoupitoulas Street. Trendy and upscale, but with more of a butcher minded menu. Somewhat similar to Abattoir in ATL. Might be a good change of pace from seafood, or a place to stop if you are in the warehouse district checking out galleries.

Luke: John Besh is probably the most famous chef currently in New Orleans. Luke is his french brasserie. It is downtown in the CBD near the Marriott and Canal.

August is another Besh establishment that has won several awards

He also has a few other places in town.

Bars:
You pretty much have to go to Pat O'Briens in the quarter and drink a Hurricane. Its on Bourbon. They have a great patio for the daytime. At night they also have a dueling piano bar. Tip an usher and get him to find you seats. The piansts are usually talented and play all the creole and zydeco classics as well as take requests.

Other Attractions:
New Orleans French Market: This is near Cafe Du Monde on the edge of the Quarter. Great place for people watching.

St Louis Cathedral: Cant miss this. It towers over the french quarter. Has adjacent square and gardens that are beautiful. Lots of street performers and such in the block or two surrounding the cathedral.

Art Galleries: There tons of wonderful galleries in the Quarter and the Warehouse district. I would think most would at least be open for limited hours during the day, even during mardi gras. One of my favorites in the Quarter is the Michalopoulos gallery.

Tchoupitoulas Street dead ends into Canal, and if you walk up Tchoup it is also lined with galleries.

Harrahs: giant casino in the heart of the CBD near the end of Canal by the river, if gambling is your thing.

Shopping: The Shops at Canal Place is a fairly upscale mall near the end of Canal by the river. They have Saks, etc.

General Advice:
All sorts of great shops and galleries in the Quarter, if you dont want to encounter too much of the drunk mess though, I would steer clear of there later at night. The quarter is great during the morning and day to wander though and take pictures and check out the galleries and shops.
Uptown and St. Charles street specifically have beautiful old plantation homes. There are lots of parades there as well. May be worth a cab ride. I would really stick to the main streets of the CBD, Quarter, Warehouse District and possibly Uptown though. The main thoroughfares of the neighborhoods I mentioned are pretty safe, but it can get sketchy fairly quickly once you get off the beaten path. New Orleans is definitely not the town to go exploring in at night.
Let me know if you have any questions. Have Fun!
