Digital BW, The Print

I'm considering a change of inkset to UT-3D, using the
PrintFIX Pro with the extended grays target to generate a
color profile, printing with the standard Epson driver, and
tinting in Photoshop. The advantages of this approach
seem to be: a fully color-managed workflow with the
standard printer driver, only one profile per printer/paper
combination, (rough) monitor/print matching on tints
without needing soft proofing profiles, ability to generate
web images that match prints.

Has anyone tried this?

I have two concerns in particular:

1. What's the best way to tint in Photoshop to keep within
the ink gamuts? Is this easy to do?

2. How do you handle glossy papers? Will I need to install a
photo black? It seems that the approach Paul Roark
suggests of using Eboni on glossy paper (using dark grays
to add density?) might not work in this approach.

In particular, I want to print on Innova Fibaprint White
Gloss. Maybe this will take Eboni OK anyway?
