I own both Marovic and Parma and Uhlmann (well, his later version in German, A Lifelong French); both are good. Psakhis also has good coverage, probably the most complete and systematic around.  

4...exd5 is very respected theoretically, but playing with an IQP as Black is simply not to the taste of many players. White's queen's bishop will be free (in contrast to Black's in the QGA); there are early pins, pieces can get exchanged--one doesn't exactly get monstrous attacking positions automatically. The White Tarrasch player is often a positional or technical player, and trying to manage an IQP, with an endgame advantage in prospect, might be to his taste. One the other hand, after Black recaptures with the queen this conservative player can find himself in a Sicilian-like situation that may be exactly what the Doktor did not order.

Uhlmann's "Winning with the French". It's also recommended in Marovic and Parma's "An Opening Repertoire for Black", but that's only a small part of the book (14 pages). Both books are out of print, I fear.
