Sounds like you have it right. As far as water changes go, weekly is fine unless you see an ammonia or nitrite spike. You shouldn't since you are moving the filter media over but you still need to test daily just to be safe. If you don't ever get a reading for ammonia or nitrite, then its just weekly maintenance.
One other thing. You mentioned running the UV steilizer 4 hours a day to prevent algae. The sterilizer will only prevent free floating algae (diatoms) that are responsible for green water. It will only kill what passes through it and most algae isn't free floating but attached to plants, tank walls, etc. The sterilizer won't have any effect (or minimal at best) on other types of algae.
