Materials help needed

I want to build a simple 8 x 8 shed/coop hybrid. Simple meaning no insulation is needed. I want to build it "kit style" with screws so it can be disassembled fairly easily. I am looking for any help on materials that would be useful for this type of project. The demensions I want are 8x8 7ft peak of roof height 6ft lowest part of roof height. I will be doing a lean to style like this: http://www.americanstoragebuildings.com/images/Sheds/specialty/8.jpg except with 2 windows and 8x8 demension.

Any help on materials I might need, specific good screws or hardware or even types of plywood. The floor will be plywood. Or if anybody has any larger size shed plans or even 8x8 coop plans but I need more shed style to walk in and such. Thanks for any help!
