Bad luck Todd. N. bicalcarata is one of those species that is usually not possible to save when it's in the state you describe. I've had similar problems with repotting really large plants, they don't seem to like the root disturbance at all. Doesn't seem to be the case for smaller plants though.
This is a species that really sucks up water if the humidity is a bit low and if the roots happened to be damaged too, then, well... Guess it's too late now but I would have tried trimming some of the leaves back at the first sign of leaves curling, either that or put water in the pitchers.
