Digital BW, The Print

I am pleased with my first attempts with my black only using 
claytons jones workflow with my 2200, ps8, winxp and matte black 
epson enhanced matte, and haven't put in my newly arrived eboni 
black yet but am interested to know what all the other options are . 
Printing b/w with all the colors certainly had an unacceptable 
magenta color cast that I am not prepared to fiddle with when I can 
get the bw with black only 
but i keep hearing reference to quad? UT2 ? peizography? etc
is there a summary of the diffferent options and the plus and 
minuses of each?  Or should I relax and enjoy what I am getting so 
far? Is the grass is not all that greener on the other side?
