Mep319, I dont know of a specific thread that will answer your concierge questions. Perhaps you should just do a blanket search here on the Dis based on the word concierge be prepared for lots of threads to pop up.
Regardless of whether or not Im staying in a concierge room, I make my room requests at the time that I book my reservation. Once my request is in the Disney reservation system, I try not to fret about it (Im too busy fretting about everything else). You can certainly relay your request to the concierge; Im sure they will try to make sure that your request gets honored (but remember, it is only a request).
When I have asked the concierge to do something special for me, they have always asked for my credit card information, and I have always given it to them. I have not asked for toys waiting in my room, but I know that other folks have. Since you already know that you would like a Safari Mickey and Minnie in your room, ask them if they could do this for you (and make sure to give them your credit card information). At best, they can; at worst, you will have to pick it up yourself in the gift shop (the AKL has a great gift shop).
There are lots of special things that the concierge can arrange for you. I know that on one of my past vacations, I was planning a special dinner along the shores of the Grand Floridian. I asked for a list of menu selections and prices. It was FAXed to me shortly after my request. Right now I am toying with the idea of planning something special for my upcoming vacation. If I decide to go through with it, I will definitely ask the concierge to help me arrange it. If I decide not to go through with it (it might be too costly for my tastes), I will probably ask the concierge to suggest some other fun things to do instead. They usually can suggest some really wonderful things (and some things that I have not thought of before).
Now that I have said all that, in my humble opinion, the AKL has the best concierge staff on property. Please relay your room view request to them and dont forget to ask them to make any Priority Seating reservations for you. Have a magical vacation.
