You are going to have to do some research and reading on your own. While we can give you suggestions, ultimately, you are going to have to get your own space set up. It is important to understand what you need to grow great bud and the biology of the plant.
Tell us more about this space. Is this a closet area? The area you are talking about is not really that small. Converting to dimensions that I can visualize, I get approx 6.5' x 4' x 7'. Depending on how the door is situated, you may be able to have both a vegging place and a flowering place, which is what I prefer.
What is your budget for this project? I'm with Hamster on the grow kits. You are far better off buying things "ala carte". Some of the things that come in the kits are totally unsuited for what they are supposed to do, like duct booster fan for exhaust fans and pH kits that use strips rather than a meter for hydro set-ups.
