QTR-Quadtone RIP

Goin fur it. I have a couple questions on this set up to achieve the goal of drop-dead gorgeous B&W prints bigger than 13"x13" from a desk top.
Epson 3800
Ink Republic's 3800 i-refill cart system (can I get this without their ink?)
UT7 or UT3D ?
Hahnemuhle Fine Art Baryta, or similar luxurious paper.
I am concerned with longevity but want a deep black, smoooooth gray ramp and a neutral color as close to my darkroom silver prints as possible.
It will be up to me get the numbers with QTR but I'm looking for the best starting point with materials. 
The drop-dead gorgeous part will be encouraged with the wine I provide : )
