I checked out an anthology of all of Bradbury's work from the library and I love it! I especially like how many Mars stories seem to fit in a single narrative, like "Mars is Heaven" referencing "Earth Men", and maybe "Dark they were, and golden-eyed" fits in somewhere. Is there a good ordered list anywhere?
Bradbury's collection The Martian Chronicles was supposed to be a chronological arrangement. For instance, in my copy, "The Earth Men" is the 4th story, dated August 1999, while "Mars Is Heaven", under the alternative title "The Third Expedition", comes 6th, dated April 2000. I would say, then, that the table of contents of The Martian Chronicles is your good list.
Edit. To save this from being a "link-only" answer, here is the chronological list from Wikipedia. There are two alternative years for each story to take place, because the dates were moved 31 years futureward for a 1997 edition. I've added Internet Archive links for most of the pulp magazine stories.
