Looks like a red to me as well. Every pup adjusts differently, but most don't take long. Couple days, maybe. Some seem to adjust instantly.
As for toys - I'd skip the Kong until he's a bit older. Focus on puppy safe chews (there are tons out there). They will come in very handy when working on the typical nippy puppy phase as well. I personally avoid anything stuffed, especially with young pups. Perhaps even a smaller tuggy rope (you will need to get new ones as he gets bigger/as they become extremely worn).
I always start crate training right away. It really helps with house breaking as well. Try to avoid putting food or water in the crate with him and NO toys. What I've always done is give a treat when they go in so they associate the crate with positive things and use a command "kennel" "crate", etc. I also start working on teaching exiting manners right away so that the pup gets the idea when they are small that they are not to just push out of the crate the second the door is unlatched. I use towels for "bedding" with pups as they are easy to wash and you can usually find some for cheap, just keep an eye on him for chewing them up. Definitely put the partition in, as too big of an area makes them more prone to pottying in the crate. He will likely cry at first, ignore it. He will settle down and get used to it.
Food will need to be a slow and gradual change, I'd give it a day or two and then start the transition. Here again, every pup is different. Some can transition faster than others. Just keep an eye on his stools, if they start getting loose, slow the transition down.
