What I would suggest is to use the B&W panel slider and especially the little targetted adjustment tool (top left). With a face like you describe, I'd be dragging the tool upwards on the face, which would be lightening how reds and oranges (etc) are rendered in grayscale. The beauty of this tool is that it lets you keep you eye on the image, not flicking back to the panel, and as you drag the cursor you see how areas of colour are converted and how the grayscale composition changes.
I wouldn't be looking at presets until I was confident with this - and making my own presets. Remember that the same film stock can produce very different tones depending on whether you used a coloured lens filter, and grain will vary wildly depending on your choice of developer, dilution and agitation.
