No longer a newbie, moving up!
I think business is such a loaded word. So many people say they intend on starting a business and really mean they are going to try and get a few portrait clients and mabye a wedding or 2. When you say you want to start a "business" it generally means you mean to try and make your livelyhood from this venture. I think for anyone to help you properly you need to define exactly what you mean by "business" and then people can help you better. By the way in my personal opinion you are severly under-equipped for any kind of professional photography venture and unless you intend on charging very low rates you would be doing any potential client a disservice. If you look at my sig you will see a decent start for what you need but it is definately still not exactly enough.
