Hi Predator, it's our pleasure to answer your questions, especially if it's about nepenthes. Sadly, I stay in a tropical country so I have absolutely no idea of how your four seasons conditions would be like! If you refer to direct sunlight, yes it means the full sun shining upon the plant. But, I believe that in your conditions, you should expose the plant only to morning sunlight or evening sunlight as afternoon sunlight will literally burn the plant.
Pitchers should only be cut off if the entire pitcher has completely dried up. Sometimes, the top half of the pitcher will dry up, leaving the bottom half of the pitcher still alive. Usually, the pitcher will absorb every single bit of nutrient as long as the bottom half of the pitcher remains alive. Good examples of such pitchers would be the species N mirabilis. Cutting dead leaves are alright and does not seem to affect the plant.
I have never cultivated Lady Pauline before, but it will certainly be easier and more vigorous compared to burbidgeae and maybe jamban. All nep hybrids tend to show more vigour and easier growth compared to their parents.
I think your conservatory would do better with highland nepenthes, though I do believe that during summers, it can get really hot as well. Generally, keep humidity above 50% for best results. Highlanders do best if there's very high humidity level in the night, 80-90% (or even 100% if possible). Try not to expose your neps to really strong light. Good luck!
