One minor note about the hammock - Check it daily for chewing. Even if you've had it six months I'd keep checking daily.
Our robo girls recently went a bit mental and went from climbing on the hammock to eating as much as they could in the space of a single night, so I think checking daily is really handy. I had checked it the night before, but then we suddenly had three or four holes appear, two of which were quite big lol
They're great, but some hams chew them and then they're best taken away. We use them in two cages at the moment though (for our syrian and our male robo) and they're great if the hamster doesn't try and eat them lol
Other than that minor warning, I think all sounds great
