For that shot of the engine, you are going to need to step up the shutter speed. Everything looks washed out because there was so much light. Also, drop the exp back down to 0. With that bright of a day, you shouldnt need to mess with it.
Well it is a users guide, not a how to. That is a good camera. You can use old Minolta lenses with it and there are tones of them around.
As far as the settings go, leave it in auto/auto no flash till you get used to it some more. Just go out and take pics, that is the best way to learn to use it.
