Some of the things that you could do are interesting, but at what point are you throwing good money after bad? If it is a personal mission, go for it, but if you are just trying to get stuff back so you don't have to buy new stuff, it doesn't seem cost effective. Also, if the insurance company paid you, they might have a right to the stuff even if you do find it. That's the way it is on auto losses, but I dont' know about theft. (i.e. if they total your car and pay you for it, the insurance company then can take the car and salvage it or scrap it)
