Someday, there might be a Promethean Age collection, but don't hold your breath!
There are also a couple of short stories related to The Edda of Burdens. "Ice" is a first-person version of the first chapter of All the Windwracked Stars, from Muire's point of view. "The Devil You Don't" is a bit of her history, also in first-person. That fiddle shows up in All the Windwracked Stars, incidentally.
Two stories related to the Jenny Casey books have been published: "Gone to Flowers" and "War Stories." The first was published in the Australian anthology Eidolon, and the second in Jim Baen's Universe, an online magazine.
In addition, there are two short stories that are only related to each other: "This Tragic Glass" and "Ile of Dogges," which involve time-traveling historians and Elizabethan poets. The second of these was written with Sarah Monette, my talented and charming and very, very smart writing partner. Her website, Labyrinthine, is also full of cool stuff.
