The real issue in my case was something odd about the JPG file. The ePUB plugin for Firefox displayed the cover on page 1, but Digital Editions (and the PRS-T1) did not. After cleaning up the JPG file format using jpegtran, the covers were correctly displayed on the PRS-T1 and in Digital Editions.

I don't know what was wrong with the JPG files, but running jpegtran with -optimize, -progressive, and -copy none fixed it.

PS - when converting a book individually, you are given the opportunity to change the cover, or add one if there isn't already one assigned. I already had covers assigned to the books, so that wasn't the problem. There is also an option to not include covers (either in single or batch conversion) but I didn't have that checked.
