Hi Bobby,
Sounds like you've got some pretty solid advice so far about what to expect re preparing for the pup - I'd just like to add that you may want to consider arranging a vet visit for within the first three or so days of bringing the pup home, just to make sure everything's in working order and there aren't any nasty surprises lurking around the corner.
About the kennel, you can buy them from pet stores, but they're generally pretty overpriced and don't come with a run. I made one myself for Lola (my Shepherd cross) out of some planking and chicken wire that I got from the DIY store. I made the kennel itself (where the dog sleeps) like a long oblong box. I made it with quite thick wood, and nailed some carpet onto the inside walls, ceiling, and floor (to prevent the cold seeping through). The run itself is about fourteen feet by five feet, with the kennel in a back corner. I attached my run to the house, sharing a wall (so I had to build less walls for the run!) and is made out of posts set in concrete in the ground, with several layers of wire so Lola can see out but not escape. The walls are pretty high on mine, but judging from the contributing breeds to your pup, you probably won't need to worry too much about jumping (from my experience with Danes and Labs, they're not great jumpers - not sure about Dobermanns though and obviously it's up to you).
Anyway good luck with that - if you really don't have a clue about carpentry or anything like that, you can hire someone to do it for you, but it's not that difficult - just use your common sense, really (for example, presuming your garden is fenced, you might be able to place the run in a corner, thus removing the need to build too many walls yourself).
