I also suggest using a hydroponic method for indoor growing, as it is much more productive than soil based growing. I would google around and look at some of the systems that are available to get an idea of the size you need. After looking at them I would then suggest building your own. Most of the systems are really overpriced. Theres not much more to a good system other than a small fountain pump,buckets and some tubing. As far as the media being used,yes rockwool is a good option, but I prefer clay/terra cotta pebbles. Aside from the fact that rockwool dust is pretty bad to breathe in,the clay pebbles can be used over and over again and are easy to sterilize. Dont skimp on the PH meter. Controlling the PH and EC levels are one of the most important things you will do while growing hydroponically. The other thing that is going to cost some money is the lighting system. You can find used HPS lights on Craigslist. The indoor pot growers are just now realizing what commercial growers have known about for some time,LED lights are the way to go. These LED lights have many benefits including longer life,better spectrum of light,less noise(HPS has a loud buzzing ballast) and far cooler operation(again HPS get very hot).
Ill get back here and edit in a link for you once I find it. I have worked with a company that deals mainly with commercial produce growers, but as I recall they have a good home/hobby section as well.
Also look for seeds that are specifically geared toward indoor growing. The plants tend to be more compact and tolerant of the lower humidity levels inside a home. If you have trouble finding seeds I can help out. As Steve P noted I do grow a wide variety of peppers and source seeds all over. The Bhut Jolokias(Ghost pepper) seeds I found were from a guy in India. He said they do not eat them,but grind them up into a paste and paint the fence post around their fields to repel elephants from the crops.
Hers the link I was looking for

And the short one wants four whole fried chickens, and a Coke.
