Orthogonal cameras are unfortunately not yet available in Lumion, so cranking up the Focal length
slider to max is your only option. Unfortunately, the shadows will get blurrier at that range, and there's nothing you can do about this issue (the shadows in renderings do however look less pixelated than in the preview).
Regarding the background, if you make the whole sky bright white, the reflective materials in your scene will look quite bland.
I tend to import a vertical plane that I place in the background, and I then assign a Color
material to the plane: Edit materials -> Custom -> Color
You can also use your own sky dome object with a custom sky texture. Here's how:http://lumion3d.com/forum/index.php?topic=2091.
