Thought I'd cut to the chase about the thing that most people should not attempt to do without...
Otherwise here's a quick checklist. Petmate Ultra Vari Dog Kennel | Petco Store
^^^ For your car. I'm sure people out there are going to have heart-attacks, but I put in the front seat in my car facing me. Was an improvement over having to bring somebody with whenever wherever to hold the pup in the car +it still avoided carsickness issues, because my youngest guy had his chews, toys and a little bed in his crate, but he also saw me the entire time and it made for a low stress introduction to car rides. I also liked the fact that when I left him in the car while running into the store (I take my dogs everywhere) nobody could look in and see a cute golden puppy in my car, even with me leaving the windows cracked open.
Toys - for very young puppies, I'd somewhat approach the same way as babies. LOL. Crackly toys, rattly toys, squeaky toys, different materials, textures, etc. Aim for stuffies of different sizes, but also crinkly toys really went over well with my youngest guy when he was a puppy.
Chews - go for different kinds. Seriously. Don't just get nyla bones. Also try to go to smaller/holistic type stores. You're going to get US made chews there and avoid the China made stuff you'll be stuck with at the bigger stores. When my guy was a pup, the big hits were edible bones. They were hard enough that he had to work on them quite a bit before nibble bits off. If I were getting puppy now, raw bones similar to what my older boys get would be a big deal.
I buy beef bones that are sold on Sunday/Mondays at my one grocery store. There's a little meat on the bones + they can work on getting the marrow out. Be cautious about bones wide enough for the dogs to get their jaws stuck inside the bones, but that's about it.
Also talk to your breeder right now about what puppy food she's feeding the pups.
You want a plastic container (vittles vault is fine) and generally to keep the food fresh longer, I get one big enough that I can put the whole bag inside and shut it up.
I transitioned over to adult food by 4 months... so we literally just went through a very big bag of food between 9.5 weeks and 4 months before we transitioned to adult food.
You also want to visit the baking section at your store and pick up measurement scoops. Plain old plastic scoops with 1/4, 1/2, 3/4 measurements are ideal.
You will generally start off feeding a pup about 1/4 to 1/2 cups of food per meal (3 meals a day). That may go up to 3/4 cup per meal when the pup grows. And then 1 or 1-1/2 cups per meal. But having exact measurements is a good idea to prevent overfeeding.
