Remove dead pitchers and blackened leaves with a sharp scissors, dip plant in a root stimulant (like Superthrive) and repot into small pots with either LFS (long fiber sphagnum) mixed with perlite and fine orchid bark. Or just LFS alone.
Keep moist by placing in a well lit semi humid area. A plastic clear tent over growing area will help reduce transpiration and wilting. Water every day but allow excess water to drain away.
Slowly acclimate them to more light and less humidity. Be sure to fertilize with a dilute fertilizer TO THE ROOT AREA ONLY), as spraying ferts (SALTS) on the leaves or in the pitchers will burn the plant.
Once the plant begins to grow and show signs of new growth, acclimate them to a brighter lit area with drier air. Plants will adapt with the nutrient rich soil in the rootzone.
Repot when plants become root bound into a media of your choice and don't forget to fertilize IN THE ROOT ZONE ONLY!
