I went on a tour of Belleville a few days ago that a friend of mine had heard of. The Parisian guide was very funny. He had other suggestions for places I had never heard of before, cant rememeber the name, I was there only for a Few days, but you can check his website (the guide's name was Julien) http://paris-in-sub-version.com
There is so much going on in Paris that it's hard to keep up! I'd recommend using the gogoparis website - they have a calendar of events (in English). They also just launched a downloadable guide to Paris with a whole section dedicated to what's on that month. Very good stuff!
A Bike About tour of Paris is a nice way to orient yourself with Paris. Paul, part owner of the business, as well as tour guide, is extremely knowledgeable and will show you a side of Paris
