Must Have/Favorite Gear for Pups

I'm bringing my 8 week old pup home in a few short weeks. I've been stocking up on supplies/toys but want to know if anyone has any "must haves" that you or your pup loved. I'm not a novice to puppies/dog training by any means, but haven't had a puppy in almost 5 years. My Aussie ended up being super easy, but I'm expecting my GSD to be a challenge (nightmare lol), so give me all your gear recs!
