Scott, you will want to avoid Procharging a stock 496. Internals will not take the boost. You are better off looking into a Raylar kit for your motor. Plenty of info on this in the tech section. If your transom looks like what I think it does, I'm not sure you have room to install external hydraulic steering. Won't be necessary unless you get the boat running 70 MPH or above. The Bravo III X should live if you are kind to it. Might want to consider moving to a Bravo I if you are looking for top end.
