Paris - Flea Market Highlight

I'm so excited to leave for Paris next week! I haven't done as much research yet as I should on places to go and things to do, but I have been scoping out the flea market scene. I can't wait to give a first hand report on the Porte de Clignancourt (Les Puces) flea market next week! Here are some pics from Paris Perfect to tie us over...  

If any of you have suggestions on Paris shops/bakeries/general shenanigans that I simply must experience, please advise!
