As you've noticed, C-41 film isn't really black and white emulsion, and it doesn't respond to printing in the same way on black and white paper either. I have used it, and gotten decent results, but when I do use it, it is specifically because I don't want to process it, but would rather send it out. I don't do much of that these days. There is also much less flexibility in development using color process. If you are seriously interested in black and white as a medium, I would earnestly advise mastering regular black and white processing and printing over using a color process monochrome emulsion. Plus, nothing is cheaper.
If you are dead set on doing it, I'm sure more good advice will appear on this thread.
