i don't know how they can call themselves a print-shop without any (or lame attempt at) calibration, find out what they print with, and use that profile, i've never done neg's, but i know i always have to adjust the highlight, midtone and shadow areas, to suit my printing conditions (not my monitor) i use grey ballance tecniques. one you have a profile you can use the info pallette to see the % of cmyk values of 5%, 50% and 95% values in greysale (black) use those numbers to adjust the highlight, midtone and shadow areas,of your image, for each ink,
Each image may have different densities, so actions aren't really an option, unless you can make a script that scans for the darkest area and non-specular hilights...

this is just a small sample of somthing resembling assistance
