QTR-Quadtone RIP

Okay, here's a couple of oldbie/newbie questions

Basically, for a number of reasons, I haven't used QTR for so long it's 
all changed...!

So:

1. You don't necessarily need to use three curves - you can just use 
say 2? (as well, is there much need to fiddle with the Split Tone Curve 
Blending if you are just aiming for a slightly warm above neutral print 
for example? or just unchecked it and leave the 
highlight/midtone/shadow sliders linked?)

2. Do you still need to apply the QTR matte/glossy profiles in photo 
shop etc? Or do we just use straight gamma 2.2 files now? (couldn't see 
anything in the existing documentation?)

so yep - it's been a while....
