Digital BW, The Print

If you start with a black and when negative that scanned as a color 
image, do you convert your image to grayscale before sending to the 
printer?

The reason I ask is I'm wondering how to correct a color cast in a b&w 
print.  If it's already gray scale, how do you correct the (magenta) 
cast?

There is no "cast" if you select "black only" in your printer. 

There is no "cast" if you save your scan to TIFF and print with QTRgui.

Your "magenta cast" can be eliminated from your monitor, but that
isn't necessarily important. 

It's easy to scan a color negative or slide, save it as a TIFF, see it
in vibrant technicolor on the monitor (you don't need gray scale),
visualize B&W (exactly the way Ansel Adams would have outdoors, before
ANY electronics), adjust using Photoshop or Elements by
trial-error-experience, and print beautiful untinted "archival" B&W
using off-the-shelf Epson OEM pigments (and probably every other
printer's own)either with Black Only technique or with QTRgui. OR you
can make things complicated :-)
