Quote - BadKittehCo, "the end user sees and gets one jpg for diffuse, one for Bump... and often something for specularity and displacement as needed...  and any transmaps"

Precisely so. The finished maps are saved out as jpg in 3072x3072 at 75%, except for displacement that is a tiff file.

Yep yep, that sounds almost like the same thing I do (my resolution varies based on what is needed, and 'save for web' jpg at High seems to give me best compression vs. loss ratio. 

Displacements don't do well when they are not in a lossless format (like tiff), compression artifacts end up becoming additional random bumps and creases and other crap on the mesh. I do save the tiff as grayscale to save space.
