I had bought the smaller plastic pen before we brought Brodie home. Might work for a single dog, but not with 2, at least not with our two. Kooper was able to push that all over. It is now split apart and serves as 'gates' to block off areas of the house. I do have the metal one and have used it in the summer in the past, might get another to make a larger pen for these two, we shall see.
We have a bit under and acre and no fence. I just take Brodie out on a retractable leash to go potty - no big deal, I always have with Kooper too. This way he is brought to where we like to have the dogs potty, yet gets to run around a bit and I don't have to run around after him.
Find out what the breeder is giving for food, buy a bag. If you will continue that, great, if you want to change start thinking on options as there are a ton.
I wouldn't do a bed for the crate just yet as puppy may pee on it or chew on it. Personally, I would wait and see if he she is a chewer. I bought these

and then had an older towel on top. We started out with an airline kennnel but Brodie did NOT like the enclosed plastic. He was just fine with a 22" wire kennel with a blanket over top though of the back half. He is now in a 24" wire kennel and I completely cover him at night since he is in our room.
Potty treats! We started out using kibble, but then moved on to Zuke's puppy treats. I cut each in 4 pieces when he was littler, now he gets 1/2. He got more excited about going outside once we used something just for potty time. The Wellness puppy treats are super soft, but they give him the soft stools even when broken up into 4 pieces.
We used this collar with Brodie and he recently moved up to a new one. It was small, lightweight.
