We loved Paris, even though we don't speak a bit of French. We were a little afraid of the rudeness at first, but we found that most people were very friendly. We only had a problem with one waiter, whom in my opinion screwed up our order on purpose. Other than that - no issues.
The best thing you can do for yourself is take a guided tour. We used Les Cars Rouges, which takes you to all the main sites via bus. We went to the Eiffel Tower, Notre Dame, the Arch of Triumph and some other sites. We also booked a tour that was just to see The Louvre. We were so glad we did this and loved the tour because the line to get into The Louvre was outrageous and people had been lined up for hours, waiting to get in. With the tour, we walked right in, with no wait. The guide took us to famous paintings and gave us information that included the history of the paintings. When the tour was over, we were free to remain in The Louvre and see what the tour had not shown. We also took a tour to Giverny and visited Monet's house and gardens. I highly recommend this if you go to Paris in the Spring because the waterlillies and gardens are beautiful.
The reason I loved the guided tours is because they gave us so much information and history that we would not have known had we gone to each attraction on our own.
One of my favorite places in Paris was Montparnasse. We bought several tapestries at great prices. You can go to the top of the hill and there are local artists there painting with pieces for sale.
The food was very good. We particularly enjoyed the Fixed Price meals where one price got you a three or four course meal.
