replacing the whole dash is alot of work, you can buy a dash cover though. they make a carpet one and also a new plastic one you can silicone on top of the old. the speakers could just be a broken wire, same thing with the windows, could just be a short. as far as the loose steering, how much are you talkin? you can try to tighten up the steering box some to take some of the play out, but you may wanna look up RockSolidRamSteering. it basically replaces a bushing in the steering shaft to get rid of the play.
