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, is a good potty solution if you will have your puppy using the potty inside when the puppy comes home. This is what we use here in the playpen and the puppy will identify the tray as his bathroom.
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.
I place the Kongs in an empty egg carton so that they stay upright and don't spill the filling in the freezer.

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.
