Digital BW, The Print

Dear all,
  I'd like to get some more rigor in my printing process, and I just
don't know where to start.

Which is more important -- to calibrate the monitor, or profile the
printer?  Or are both necessary?

Is it possible/useful to go to a "color-managed" (really
luminance-managed, I suppose) workflow without a densitometer
or monitor calibrating device?

Thanks!
