Digital BW, The Print

New to the group.  I print BW using Epson Printer 7600 UltraChrome, 
ImagePrint ColorByte 6.0, Epson inkset with matte black,ColorByte 
gray profiles with no tint on various matte papers.  Also color on 
matte papers.

Wilhelm has data, obvious reasons, only on Epson print driver, ink 
and papers.

Does any one have any permanence data on my configuation for BW and 
color?
Are Epson gloss black, matte black and light black pigmented inks 
per carbon?
What do you recommend for gloss black and white for my configuration?
Do you recommend any other inksets, profiles for the Epson 7600?

A lot of questions, but would appreciate knowing the answer to any 
one of them.  Thanks
