render screen all grey in preview, won't matter if i change Tone Mapping

Hello everyone, I am a newbie and I am stuck a bit. I have placed 3 objects in my scene and the render just won't happen. I post a screenshot so that you can see what i have to work with and perhaps help. I wouldn't want to restart the scene from scratch especially because it's painful to zoom out to such a distance for the image i want to render.
Non related to the problem but, is there a way to quickly zoom far far away with my point of view? As if i close and re-open the program and load the scene the POV is not as it is in my screen shot and it takes like a few minutes spinning the mouse wheel to get to the view I want.
Thanks for any help :)

You don't need to worry about losing your scene. This is also not a tone mapping issue.
Please get back to us with the stuff under "2" and we'll see about sorting you out from there.
Also, you're camera is set to a 'bottom' point of view, below DS' 'groundplane'. While this plane appears to be transparant in preview, it is NOT in a render... regardless if what camera you use.
