QTR-Quadtone RIP

As a newcomer to using QTR (2days) I am trying to get to terms with curves and adjusting QTR to give the best print. I can get the brightness levels pretty close using a scanner but am finding colour casts very difficult to remove. My questions are:
1. will using a 2880 curve for a known paper work pefect with my image-life CIS inks both in terms of brightness but also colour?
2. Has anyone else produced curves for image-life CIS inksets for the 2880?
3. Will 3880 curves work well on the 2880?
4. Is it possible to hire a spectrophotometer or densitometer?

If I have posted a message that has been covered multiple times before I apologise but I can't find it when I search.

I am starting to realsie how much I don't know about b and w printing and hope that this forum may help thanks
