Looks good so far. I cant give much advice on nutrients, soil and general plant health. but I do like the CFL's. I was in tool and die / industrial maintenance for years. I like how its all neat and tidy and somewhat modeler.
Things to look into from a mechanical standpoint would be:

-Air circulation. The more "stealthy" you go the more important air circulation will be.
-More flexibility in lighting positioning may be desired as the plants grow. You wanna have those lights pretty close and somewhat evenly distributing light to the plant for efficiency. You can rotate the pots and there positions daily or so to help with that also.
-Don't forget to figure something out for smell down the road. That will really put a hole in your stealth.

But from one noob to another that looks like a great start!:thumbsup:
