Frist of all I'd like to say WELCOME! Now for answers to your questions. You are correct about the streaching due to the lights being a foot away. Now to get the most use from the lumes from your cfls keep the light 2-3 inchs from your plants. Now the lights will Surfice for the frist few weeks but investing in a few more will help alot. As far as the kelvin for veg and flowering you were correct but it never hurts to have more. Now when you get more cfls it won't hurt to mix up the daylght and warmlight gets the best of both worlds. Any other quesions ask away
