Digital BW, The Print

I am just getting into black and white digital scanning and printing 
after years of traditional darkroom work. I am trying to learn 
photoshop with the Classroom in a Book book. While I am learning it 
this way, I feel like I am spending too much time on stuff that 
doesn't apply to B&W photo work. Can anyone suggest a good book that 
focuses on learning photoshop for photography and preferably black 
and white photography. Thanks. Paula
