Digital BW, The Print

I'm using MIS EZ inks in a C86 with Paul's recommended Epson driver 
settings, and I'm trying to match Paul's color settings. Question 1: how 
do I check what the embedded profiles are when I'm ready to print? (Paul 
says, "When printing, see that no other profiles are embedded in the file.)

Questions 2: Are the following Color Settings correct?

Working space:
RGB: Adobe RGB (1998)
CMYK: Photoshop 5 Default CMYK
Gray: Gray Gamma 2.2
Spot: Dot Gain 20%

Color Management Policies
RGB: Preserve Embedded Profiles
CMYK: Preserve Embedded Profiles
Gray: Preserve Embeeded profiles.

Conversion Options: (Although I don't think these will do anything 
because of my color management policies. Is this correct?)
Engine Adobe (ACE)
Intent: Relative Colorimetric.
Use Black Point Compensation and Use Dither Checked.

TIA,
Peter
