I find that getting my fit adjusted right after switching shoes or pedals very difficult. I replaced my old shoes mid January and still don't feel like the adjustment is just right. My advice (maybe too late) is to try to notice as carefully as possible where your foot is in relation to the the axle on the old pedals (I use the tip of the rounded protrusion on the inside of my foot, just back from the toes, as a reference), and possibly even marking it on the shoes. Then, notice distance out from the crank and try to duplicate that in the new setup as well.
