Hey Jaws,
Looks like you have quite the setup planned. There are a few things that we need to know first to help out where you can properly support this project. However, I am telling you now that you are probably going to lose your bottom patio doing it.
What type of earth do you have under your concrete slab? Is there much clay, approximate level of the water table where you are at? What type of wind loading are you going to be seeing on the walls of this project. What speed?
First you have to look at the stringers that you currently have in place. They are in no means a way to anchor something that big, and to ensure that you don't put excessive loading on your exterior wall of your house, you are going to want to put post supports at the wall of your house. One at each corner and at least one in the middle at the wall of your house. Considering the weight of the contents you're going to put on the deck, you will probably want to put pilings in. Another thing to look at is the sloor supports.. Might want to get engineered trusses in. The third is another post in the middle at the exterior of the concrete slab.
This may be overkill, but where I live the ground is extremely soft...lol
