Most HOB filters I've used are not very loud at all, esp. when you keep the water level close to the top of the tank. Penn-Plax is a fairly old company and I'm not sure how good the quality of their canister filter is. That canister filter is probably an old model so it may not be as efficient as a brand new basic model made by a different company. For hood setups, I prefer a glass canopy with a strip light over it. Separating the cover from the light bulb does allow you to upgrade to better lighting later on if you so choose to. As far as plants go, java ferns, anubias, water sprite, wysteria, cryptocoryne sp., banana plant, hornwort and java/christmas/taiwan mosses are good beginner plants because they are not very demaning in their care requirements and only need low to medium light levels over your tank. Some members on this website sell many of these plants in case you can't get a hold of them at a local fish store near you.
