As the manual states, your camera will work with ALL EF as well as EFS lenses, not a problem, use it as you wish, it will do no harm to your camera. Just remember that ANY lens you put on that body will have an effective focal length that is 1.6 times the listed focal length. A 75-300mm lens will effectively become a 120-480mm lens on that camera due to its smaller sensor that can only capture a portion of the lens' projected image.
A 1.6x body does not change your focal length,it changes the angle of view. It does not make your focal length change,it only crops the image.
