Prodiamine prevents germination and root growth. Trust me if you try to overseed after applying Stonewall that you're wasting your money. Prodiamine at full rate has a 6 month residual so it also means you can't overseed in the fall either.
You can apply Scotts w/Crabgrass preventor that has Tupersan as that won't prevent your grass seed from germinating. Look at the label to check that it has Tupersan and not Dimension in the ingredients.
Vita is correct, without good soil you're doomed. Once you get good soil structure and proper pH as determined by a real (ie not one of those cheap kits from big box) lab such as UNH co-op or JD landscapes good things start happening.
