Please follow the excellent advice you have been given. If you decide to repot i would gently remove any dead lower leaves.
After the repot don't water for a week or so to let the plant heal any roots you may have damaged during the process. Where are you based?can you get it in a south facing window?
If you want detail on proper watering and soil check out the two threads at the top of the forum
