If you had it alighned they shouldve set the toe into spec right then and there so you should be all set. Did they give you a print out of your readings? If not go back and get one so you know exactly how much your rear camber is out. I had mine done recently when i put my 18's on and i have yet to fix my rear camber, i'll get around to it soon hopefully, i just hate looking at my back wheels like that
