The magnification you can obtain by adding a supplementary close up lens depends on the native magnification of the lens you put it on. Supplementary close up lenses give greater magnification with longer focal lengths and extension tubes give better magnification with shorter focal lengths. Without knowing more about your lens, it is impossible to say exactly what magnification range you would obtain with a close up lens attached.
The only thing that can be said for definite, is that the maximum working distance(front of lens to subject distance) is totally dependent on the close up lens. The max working distance is the focal length of the close up lens.
The dioptre is defined as 1000/focal length. So a +4 dioptre lens has a focal length of 1000/4 or 250 mm (just shy of 10 inches in ancient US terms), and that would be your max working distance. You will not be able to focus beyond that.
