New poodle puppy-help w/ shopping?

[Dee]

I'm getting a new puppy tomorrow. He's a miniature poodle, almost 5mos of age, and very submissive (hid on me and was scared of my bf at the shop).
Question: Can anyone suggest anything to purchase that's not already on my list to have BEFORE bringing my baby home?
I know that you should try to adopt first, but all of the poodle rescues in the area only had males with "aggressive problems" or "behavior problems" and this is a housemate for me, since I injured my back and can not handle sitting normally for more than 2 hours at a time. I can't have an aggressive guy kicking my butt while I'm trying to heal for the next 6+ months!
So I got him from the most reputable shop nearby, and chose him for his submissive manner, since I am a longtime professional with pets and my specialty is dealing with ones that are fear-aggressive (which he isn't, but at least I'm well-equipped to prevent it from happening with him). I'll post my list of things I have momentarily (darned word limit!)...
Here's what I have:

small crate, bowls, chew toys, squeaky toys, one plush toy, bed, food, leash, id tag, shampoo/cond for puppies, diet they have him on (plz see my other question about the food, if you have a minute) , 1 gallon Nature's Miracle, bitter training spray, and grooming supplies. (I'm a groomer and I'll be grooming him, so that's all covered).

Any advice or ideas, pro or from experience, are greatly appreciated. Thanks!! n_n
Shelby, while I definitely value your opinion, and I agree with you wholeheartedly, I know that I can handle the submissiveness that he shows from being in a pet store so long. I would like to add that the place has been around a long time, I know MANY satisfied customers, and at least I know he'll remain non-dominating at this age. It's not something I'd recommend someone else do, but I did it because I'm 100% sure I can handle it. Still, I prefer to adopt first
My post has gotten a bit long, so I want to remind people of the original question:

What should I add to my shopping list?

ned to have a pump sprayer and a few gallons of vinegar for those accidents and plenty of news paper and something for the lil guy to aim at and remember he wont poo were he pee .
dont forget some toe clippers and get a few of the sticks that the vet has just encase you clip to close . and night lights so the dog can learn its way around better . my dogs are spoiled if a night light goes out they tell me about it . and it takes 4 to make a they plus another that is here when his pets are working .
