I would say do the lift and sas all at one time. It will probably cost less and be easier in the long run. And I think 250 springs are gonna be a little stiff, but I guess it depends what you use your truck for.
But before you do anything go here:http://fullsizebronco.com/forum/forumdisplay.php?f=29 and read as much as you can. There is tons of info on sas. Pretty much every question has been answered there already.
