I have a PROC that I am going to start programming the rule set. I want to start off with the existing Williams game rule set I am emulating. Is there a way to decode a Williams ROM to figure it out?

You can probably load roms into the debugger of your choice. Later games used some bytecode which is well understood. However, that code is not organized in a way which will help you. It might be possible to look up some cornercases but for most instances it should be much easier to just test the behavior of your game.
Definitely far easier to just play the game then hack a rom. Or use pinMame or somin to bash switches to get modes quickly.
Couple of methods comes to mind.
Option 1 visual pinball
Install virtual pinball on pc and download the William table you want to emulate and the rom file.
Using the debug option press switches and record effects (points, lights, etc).
Sound effects can be captured and or downloaded (google is you friend here).
Option 2 pinmame and rom
Download pinmame and rom
Launch pinmame and manually generate events from keyboard and record events
Option 3
Visit arcade or friend who has the game and play game and record events.
