QTR-Quadtone RIP

I've been using a prior version of QTR successfully for some time with 
my Epson 2200.  I recently purchased a 3800 and downloaded the new 
version of QTR which I understand supports three curves and allows 
split toning.  Two questions:

1.  There do not appear to be any curves yet for the 3800.  Is it 
possible to use the available curves for the 4800 for the 3800?  If 
so, how would one do that?  Do the curves have to be renamed or 
something?

2.  I have no experience with blending curves for split toning.  There 
doesn't seem to be any information in the user manual on how to use 
the new sliders in the curve blending window of the new GUI.  Can 
someone point me to a basic tutorial on this subject?  Or perhaps post 
some examples to the Files section of the group?

Thanks for the help.
