Doing it in binary would be incredibly complicated if you don't have a clue to what you are doing, so I wouldn't suggest doing it that way. Instead I suggest downloading the source and customizing it to your liking. It would be much easier, faster, and much better in the long run.
That's something I'm afraid I can't help you with. I work with SWR 1.0, and rarely have I ever used SMAUG. So I haven't a clue where to start since SWR uses the ability system and not the class system. Sorry, perhaps someone else can help?
