No. Are those the products you intend to use? You have a little overlap/redundancy. AJT wants to bond to a wax/oil-free surface. Is the purpose of step 2 to eliminate water spots from drying? If so, you can just use the OCW that way...and stop there. FK 425 is very slick and I personally wouldn't use it just before applying AJT.
If you really want to use all of those products, get the AJT on there when the paint is as clean as possible, use OCW after you wash, and 425 for in-between washes, to remove light dust or restore the gloss.
