Paul:

I'll give this a go tonight. 

I read through the instructions posted at http://www.paulroark.com/BW-Info/Embedding_Photoshop_Curves_in_ICCs.pdf and this seems pretty straight forward. I have one question:

Once the RGB-ICC is generated do you apply a curve to the image and then print with the ICC or just take the un-altered B&W image and print it with the ICC?
