You'll have more success with just the two plants, but even then I'm not sure the lighting you have will be sufficient for a decent yield. You'll have to train them well to expose them to as much light as possible.
What are the dimensions of your grow space? If you can fit more bulbs in, I suggest you do, and your plants will thank you for it in the long run. The great thing about CFLs is that they're cheap, and you have time to save up for a few more red CFLs for when you start flowing.
I'm afraid I don't use FF nutes so I can't help you on that one.
