You actually don't lose much detail if you save the JPEG files at maximum quality. You don't compress the file much that way, but you don't lose detail either. I would recommend getting the high res too, since even the bump maps come as jpegs. That way, you can use the high res for real close ups and low res for further away shots. I would also recommend getting the light texture rather than the medium texture. The light textures has more realistic elements like birth marks and such. If you don't like the birthmarks, you could always photoshop it out. By the way, the light textures do come in various skin tones as part of the package. The only real difference with the medium texture is the more flawless lack of birth mark look.
