Bronzing is a reflective color that shows up on many glossy papers.  Since
you're using EEM, what you're seeing is not bronzing in the way we usually
talk of it.

Yes, give them a try.  I'd select one that is neutral or medium warm.

You may be seeing the effects of the sepia ink tone that is in the yellow
position.  Note also that with any of the workflows it's hard to avoid a
warm cross-over in the shadows with some papers.  The black carbon ink is
warm, particularly at about 90%.  The cool toners can only counteract it
through the midtones.  So, as you approach black, the toners become
overwhelmed.  Some papers print with cool shadows.  EEM is not one, however.
This warm cross-over is going to be much more noticeable if you're using a
cool tone to print.

Good luck.
