You will need ventilation once they get going, air coming from outside and then venting back out would be best.
The last thing I would suggest you look at is a flowering lamp. HPS would be best. I use a 400 watt.
you didnt say which cfl's you have stealth hydro has a couple of pkg.deals 1 which i liked [pro315] also they have one that is a little over 488w. which i would of liked to upgrade the package to but its not in my finances it would of made it a 345 dollar price tag to get started
temp and humidity meter are nice to have. extension chords and power strips. I dont know if the kit comes with a light timer or not but you will need one of those. ph up and down all I ever need is down it depends on what your water is like. and thats all I can think of at the moment hope it helps and good luck.
