I have one suggestion........how many toys can a child play with? It might be a matter of scaling down his toy selection, putting some away for a few months then rotating them, the same with children's clothing, (for those who have mountains of laundry from your 3ft tall Divas) They can't wear all the clothes and kids can't play with all the toys they have. Scale it down. I used to have tons of laundry ( like mountains). Now when I buy clothes, I take out the old and put in the new. If I put in 3 shirts I get 3 shirts back. It works.

So best suggestion is keep it simple, simple for you and simple for him.
