Digital BW, The Print

Anybody here using Mac OS X?

If so, please excuse my beginner's ignorance... In general, I'm fairly confused 
about color management as relates to workflow. I'm trying to use Jeff 
Randall's workflow (1160; FS-N) on a Powerbook G4 (with the crappy built-in 
Powerbook monitor ... it'll have to do for now) with Mac OS X 10.1.5.

What I'm wondering is what settings I should have in the ColorSync system 
preferences panel, where I'm supposed to set the gamma (Monitors system 
panel or Photoshop, or both?), which profile to choose in the Displays system 
prefs and whether I should choose adjust/calibrate the display after choosing 
a standard display profile like Adobe RGB (assuming that's the correct one).

Other problems/questions: I use a Polaroid Sprintscan 4000 with Vuescan... 
which color space should I be scanning in (I'm mostly scanning B&W negs, by 
the way)? Should everything be set to the same color space?

What about printing... the ColorSync system panel has output color space 
options, the Epson printer driver has color space options, Photoshop has 
color space options... I'm thoroughly flummoxed.

Any help from fellow OS X users would be most gratefully received.
