Leave the menus alone, it'll do for now until you are used to the camera.
Put the dial on top to AV, this is aperture priority mode. Move the scrollwheel below your right index finger to the left, this will open up the aperture (more light, faster shutter speed, shallower DOF), move the wheel to the right will close down the aperture (less light, slower shutter speed, increased DOF).
On the top right of the camera is a button marked ISO, press this and look at the screen on the back, it probably shows AUTO as being selected - next to the screen on the back are four button arranged in a circle - press these to change the ISO setting - select 200 and press SET in the middle of the button circle.
Looking through the viewfinder, at the bottom you are shown the aperture, ISO and lots of little lines which is the exposure meter - don't worry aobut this just yet.
Hold the shuter halfway down, you'll see some red dots flash - these are the focus points the camera has found. At the same time a shutter speed will appear at the bottom.
If shutter speed is less than say 1/8th then open up the aperture, if you can't open it any further then increase the ISO setting. If the shutter speed is very high (e.g. 1/4000th) and flashes close down the aperture and/or decrease the ISO setting.
As others have said find a book for the camera - there are several guide tye books you can get for each model of camera that will help you use it. Look in Waterstones.
