Digital BW, The Print

I use InDesign CS2 on a Mac.

In the InDesign printer settings dialog, under color management, I can
set "Let InDesign determine colors", and right underneath it I can
choose the different profiles. However, my custom profiles do not show
up (in Photoshop they do...). I tried copying the profiles in all
sorts of folders where InDesign might be looking for them, no use.

Also, I noticed that while in Photoshop I work in Grayscale mode for
my B&W work, InDesign does not have a grayscale mode, I can either
work in RGB or CMYK. I somehow suspect that this has something to do
with my problem. (?)

I have a feeling I'd be better off sticking to Photoshop instead of
trying to figure out how to get InDesign to print the way I want to.
