I found the fox farm at my local nursery. I've checked Lowes, Home Depot and Wal-mart and they only seem to carry Miracle Grow for the most part. As far as soil and nutes go a nursery will have it much MUCH cheaper. The catch is that if you buy stuff online you can have almost anything you want. I see a lot of people getting their HIDs from htgsuppy.com. CFLs Bulbs are usually best bought online and in packs. Assuming the CFL wattage you're talking about is actual and not equivalent that's enough for a grow, BUT you won't have great light placement with only 2 bulbs. It's better to get smaller bulbs and have them surrounding the plant as opposed to having 2 lights at the top. This isn't true so much for HIDs because they have awesome light penetration, the only downside really to them is heat and energy consumption.
How large are you fans and how many CFM can it move? If you think heat is going to be an issue I would buy 200 watts or more of CFLs in 26w and 42w sizes. It's great if you can put out 20,000 lumens, but not so great is you're temps are in the high 90's because of it.
