Well, for a start, you've got some really good free ad-newspapers in Paris.
One quite famous is "Bonjour":
http://www.bonjour.fr

Search for "Bonnes Affaires", then "Equipement de la maison" and then "Meubles" (sorry if I sound patronising, I don't really know your fluency...)

Otherwise, what you're looking for is a "Brocanteur". Have a look there:
http://www.nomade.tiscali.fr/cat/mes_courses/commerces/brocanteurs/
or here:
http://www.321maison.com/decoration/brocante/brocante_index.htm

Or you could try les Puces de Saint-Ouen:

Hope this helps.

There are shops that buy and resell all sorts of items including pieces of furniture, maybe you can check the Cash Express shops (there is one rue Beaubourg in Paris 3, but there are others). Look at the yellow pages http://www.pagesjaunes.fr/ under "dépôt vente meubles", you'll probably get a good list.
