Fiat.....you are NOT naive. We all learn by asking questions. I find AV's to be easy. They will bloom several times a year if you keep them growing well. I would remove the moss. To me the second pot is just decorative. I water sometimes from the top and other times from the bottom. To water from the bottom I sit them in a bowl of water for about 20 minutes and then set the pot on a couple of thickness of paper towel to wick out excess moisture. When I water from the top I add water until it runs out of the drainage holes. Do not let them sit for long periods of time in the water. Every 4-5 days for water sounds fine.
