I'm new too, but this is how I would get a high contrast image as per your artwork.
Select the part of the photo you want. For straight b/w, max the contrast, for a slightly softer look, use your curves and make them vertical.
Apply a slight gausian blur (rad 1-2) to soften the edges. Assume you can do the rest of the stuff (background, text etc). If not, check out the tuts.
