I know this won't do what you want exactly, but using the Jumbotron stacks works very nicely for much of what you want: full width of browser. Unfortunately they can come close to filling the whole height but it will be a bit hit or miss depending on browser, etc. But until Adam releases his future stack this may be the best compromise situation using the default Foundry stacks.
Others who visit use several stacks from other developers: and maybe one of those stacks will work well for your purposes. But I'm not sure which will, so hopefully more savvy people can chime in.
