Digital BW, The Print

I just joined this group, and I'm hoping you can help me make an educated decision 
regarding printing software and/or inks.

I am relatively new to digital dark rooms.  So far, approximately 85 percent of my 
prints are B&W, scanned from B&W negatives.  I also use the printer for occaisional 
color prints from scanned slides.  I have tried the Clayton Jones black-only work flow, 
but find it grainier and warmer that I would like (with Epson Enhanced Matte paper, 
and Matte Black ink).  I have also tried printing with all ultra chrome inks, but either 
have metamerism problems, or the prints are too cool/greenish.  Payday is nearing, 
and I'm about to throw cash in the direction of better prints--but I'm not sure what 
direction that is.

Imageprint?  Septone?  QTR?  MIS inks?  What??

I have a Mac G4 15-inch Powerbook (1 GHz), and a 1.25 GHz G4 iMac (17-inch LCD).  
I use Photoshop 7.01 and an Epson 2200.  I also use a Nikon Coolscan 4000ED.
