Q1a) Where do you select the custom output profile?
Illustrator is not quite like Photoshop, but ACE, the Adobe Color Engine,
will allow the document to be converted to another color profile, so you
would use the RIP or driver's color management option to choose the profile
for your output device.

Don't go there... just avoid the PostScript Color Management setting, and
choose your profile in the ColorSync CM setting.

Device simulations require conversion through an extra profile, but Photoshop
can do this for images only, in version 6 using its proofing features. With
Illustrator, as long as you were defining the document for press CMYK
initially, you only need the one transform to the "proofer" profile. If you
were designing in RGB for later conversion to assorted presses, then that
would be different, and require a color server application to perform the
multiple transforms.
