Digital BW, The Print

Friends, I just replaced my Epson 2200 with a 2400 and want to print 
my color chomes in B&W. Most of my work is 120 Astia, Velvia and Kodak 
GX scanned with a Nikon 9000. I am looking for workflow suggestions 
from the scanner out, for conversion of color images to B&W for 
printing. I could do greyscale scanning of the color image, or 
conversion in CS2 with channel mixer or calculations or do the 
adjustments in color and let the printer driver do it ( I understand 
that Advanced Black and White setting will do it). I am looking to 
create a B&W file that still lets me use the most of the tools in CS2, 
especially filters, and a technique that creates a file that will not 
be automatically "adjusted" by the printer driver. Is that too much to 
ask? Thanks.
