Both come from moisture. Is water getting on those light assemblies? Keep your bilge bone dry and these problems will slow down, especially the headliner. I once had some moisture getting inside the AC space in my 3600 Open, and it only took one season for all my cabin headliner to drop. Was perfect before that. For metal surfaces, consider occasionally putting something like WD-40 or Boeshield on any plated metal surfaces you care about.
