those medium duty rear springs will "help" with sag, but not alot. the best bang for the buck on dealing with sag when loading down the back is the airlift 1000.
if you're doing the 4x4parts rear springs, i think those give you 2in of lift (mine settled to 1.5in though) so if you do that plus add the 2in rear spacers i think that will be too much for stock upper and lower control arms and being able to bring your alignment into spec. so personally i'd go with just the springs and the airlift. btw, my airlift gives me that additional .5in in the rear when fully inflated.
