Well Doug, we all know that your end results in print are superb. This 
sounds like a lot of work to get to that point. If you are
using one lab that is printing digitally (and of course they almost all are) 
they could provide you with a profile for their setup.
Assuming you had a calibrated monitor and colour management in place, you 
could install their profile to use for soft proofing. Then
you should see on your calibrated screen what their output should look like 
(within the limitations of the different devices). For
example I have a lab offering Fuji output from a prepared digital file which 
is extremely cheap. They have set up info available.
They suggest conversion to sRGB (closest to the gamut of their machines) and 
they provide a profile. If you found that with this set
up, there was a further adjustment, it ought to be consistent and you could 
routinely apply that correction. Really though, this
methods should get you very close.
Drop me a line if I'm not making sense.
Cheers
Hoppy

After calibrating the monitor with the Spyder, prints from a known
calibrated printer (the LightJet used by West Coast Imaging, which I
believe was Calypso's LightJet) were much too dark and contrasty.

My procedure now is to do a rough calibration using only Adobe Gamma,
adjust the file in Photoshop the way I want it, then send the file to a lab
with a calibrated printer.  Once I get the print back I open the file in
Photoshop, open Adobe Gamma at the same time, then adjust the monitor's
calibration (with Adobe Gamma) to make the PS image of the file look like
the print.  Assuming the initial calibration isn't quite right, I can then
tweak the photo the way I want it with Photoshop.
