I know thinking up new cage set ups can be a lot of fun & I'm sure your ham is enjoying some of your ideas but as you've only had him for three weeks I would settle on one & give him a chance to really make himself at home.
You don't need to clean every week, just spot clean pee as needed but I wouldn't do more than that for a few weeks now then you can just clean a part of the cage at a time if & when it needs it, not all at once.
Unless he pees in his nest I would leave that alone & not remove any of it for a while & never remove all of it, same goes for the food hoard, if you clean that area then always put it back or replace with some fresh mix.
