QTR-Quadtone RIP

First, I'm using QuadToneRIP Version 2.6.2.0 with a Epson1400 and
MIS UT14 inks.I have a few questions concerning the Ink setup tabs.
My first question concerns the use of the words "Gray Ink" and
"Toner" in the Curve creation process. On the first tab "Ink
Setup" the user has several choices for of each ink:       Not used
- Gray Ink – Toner - Toner 2 - Copy From - Load Curve Can someone
explain what the difference between Gray ink and Toner is and when one
is used and not another? It seems to me that with my particular inks,
they are all gray inks... some warm, some cool, etc.    My second
question concerns the "Load Curve" and how it is used under the
Ink Setup and also under the "Gray Curve", "Toner Curve"
and "Toner 2 Curve" tabs. Are the curves used or applied in
under the "Ink Setup" tab and the subsequent tabs or in just one
place. I understand how adjustment curve work, I'm just not sure
where to apply them. Also, I assume that if the user has entered values
for the Highlight, Shadows, Overlap and Gamma and then applies a curve
that this curve will them override those entries?   Thanks for the help
