Help finding and loading Models

[anklejbiter]

I've been wanting some Models, Mainly Atlas and P-body, Iron man suit, The Halo suit, The broken GLaDOS (Like you see in the game's loading screen with something hanging from her), Sora, a keyblade, a gyroscope, and a car.

I've not been able to find these, Except for the atlas and p-body as well as sora; But I can't load the models into sfm. It just won't find them, and I don't know what to do. Any help, please?
