As for the command line, looks like the process of doing multiple files is left up to the shell so windows command like psyang says or bash equivalent or whatever.
You could also morgify them, then you don't end up with a copy.

I am 99% sure saving a geotiff out of photoshop or most raster image editors does strip the georefrencing. I can check tomorrow.
Qgis desktop will allow you to do it. You could also create an ESRI world file from the geotiff, save it out of photoshop (or whatever) compressed and use the world file to turn it back into a geotiff.
