Digital BW, The Print

I would appreciate any comments on preferred workflow to convert a 
RAW digital file (NEF) to a B&W file for printing using PS CS.

Do you use the Abode RAW file converter in the browser to make some 
initial adjustment prior to importing the RAW file into PS?  If so, 
what do you do and why?

What procedure do you favor for conversion of the digital image to a 
grayscale (LAB to grayscale vs. Channel Mixer adjustment layer vs. 
Hue/saturation adjustment layer vs. other techniques)?  What 
advantages does your chosen procedure offer?

What further tweaking do you carry out using levels, curves or 
filters before printing?

I'm using a Nikon D100 and PS CS with Windows XP and an Epson 1280 
with UT2 inks and Paul Roark's curves.

Thanks,

SR
