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.
