Instead of spending hours on the 'net and in book stores I suggest you spend $100 or so and talk to an accountant about your own circumstances and where you wish to go.
If a homeowner comes here and asks questions about wiring their house the advice would be to hire a professional. I'm giving you the same advice. You can read and research all you want but in the end there is no substitute for a formal education and experience.
