This video has useful information to help you get started: How to set up a safe confinement area for your puppy. I am recommending the North States Play Area because it is safer: many puppies can easily climb the wire fence (and seem to want to make a sport of it!) I found the grass potty idea in the video very messy to clean, so I suggest using the Blyss Indoor Potty with a pad underneath the grill.
I simply can't resist sharing with you Calming Music to Help Crate your Dog. (The pretty doggy with his earphone on!)
I highly recommend the Portable Waterboy for when the puppies are small and the Slopper Stopper for when they grow up: they keep puppies' chins dry and cannot be turned into a swimming pool! The tray and shelf, with a pad on the tray, will be a better option than the Blyss potty if you will have your puppy using the potty regularly inside.
The Gooby harness is soft and great for the small puppy; the round leather collar is lightweight and does not cause matting in adult dogs.
Simpawtico has good advice on Kongs: How to Use a Kong Dog Toy.

Use this small slicker brush to get your puppy used to brushing; the grooming scissors will be needed to trim your puppy's eyes, and paws, and puppy's private areas.
Chris Christensen brush is not cheap but it's a good investment; you need a brush that reaches underneath the coat to comb where the matting starts. WALA offers a very practical grooming guide.
