a few thoughts for you -
the soil in your last two pics looks like it could use a modifier like perlite to improve drainage. also, you should only have one plant per pot - they grow way too big. you can fix both problems by transplanting into soil that is at least 25% perlite.
as for lights, multiple 42 watt cfl's are just as good and let you spread the lights around the plant.
as for your lighting schedule, most people start with 24/0 or 18/6 until the plant is ready to flower - usually a month or so. by starting out with 12/12 you will harvest sooner but the plant will be much smaller.
