Stuff on Faust:
literary and
musical.
Basically, to sort it all out, the Faust legend has been floating around since the 15th-16th century. Marlowe wrote "The Tragical History of Dr. Faustus," aka "Dr. Faustus" in 1604, and I think it was his last published work before his death. Von Goethe writes "Faust" based off Marlowe's play and a few other sources, and his work is published in 1833. Gounod writes an operetta based off von Goethe's work, titled "Faust", and it premeires in 1859. (Liszt also writes "A Faust Symphony" published in 1854, but undergoes constant revision from 1857-1861.)
