1. The Sierra Club claims three pin bindings are safer than NNN BC bindings because they can release. Here's a link to the article: http://angeles.sierraclub.org/nordic...rdic_Boots.htm
Is this accurate? I hurt my knee skiing last year, so I try to be careful.

It's antique. It's good for antique bindings, the sort of ones you see for next to nothing on Ebay. The wire has (rightly, for ski control reasons) been replaced with a metal plate clamp.
If you want a releaseable binding, the Voile CRB plate can be mounted under most XC bindings.

I don't recommend it; it doubles the binding weight, has an enormous contact point that definitely affects ski flex, and the tension of the release spring is directly transferred to the ski structure, which sometimes (air cores) cannot bear it so one is required to put a heavy metal plate on the lightest skis.

| 2. What trade-offs do you make moving from NNN BC to a three-pin setup? |
You lose the ability to make really loooong strides.
The boot flexes and might blister or chafe the top or sides of the foot with each stride if the fit isn't right.
You start rubbing the sides of set tracks unless the setter tapered them, or the snow is really shallow.
You start having a left and right ski.
You gain:
edge control
and the ability to modulate pressure on the front of the ski instead of the on/off of toe bumpers
and the ability to do it in a way that's more related to natural gait instead of standing on tiptoe.

Yep.

4. How do these look as possible setups:
a. NNN BC setup--Rossi BC X7 boot, Rossi NNN BC Magnum manual binding, Rossi BC 70 AR Touring skis (70/60/65 179 cm). The BC 70 ARs look good because they can still be used on the groomed tracks if I want to.
b. Light tele setup---Voile Hardwire 3 pin binding, Rossi BC x11 boots (or Scarpa T3 if they're available?), Rossi BC 90 AR Touring skis (88/60/78) or the Fischer Boundless Crown (98/69/88).
Any problems with either setup? Which one is more versatile? Recommended gear additions/deletions/substitutions? Do these setups make sense?
Thanks again for all your help.

You missed a boot/binding combo in there:
Rugged touring boot category: Rossi BC X9 , Alpina BC 1575/2075, there are also double leathers by companies like Asolo and Alico.

3 pin no-cable Bindings: Rottefella (sometimes Rossi) Super Telemark/ Voile HD Mountaineer

(of those 2, I like the Rottefella for bail clearance to 20mm lugs, though Voile have a complete line of accessories like lifters and things. The Voile 3-pin light cable bindings mount to the same holes.

And you can always take the cable off the hooks for the uphill bit.
