I'm a couple of weeks ahead of you on this one but from reading around, you pick up a lot.

Q.1 Do i put them under 24h light whilst in the paper towels?

No, leave them in a dark warm place.

Q 2.Do i use all three lights or just the cfl's?

Not needed when in paper towels

Q.3 How big should i let them sprout before i put them in soil?

Wait until the seed cracks and it has a white tip.

Q.4 How long do i leave them under 24h light ?

That's for the vegetative stage (once they come out of the soil). You veg stage is until the plant is a foot or more (but it depends). You can also do 18hrs of light, 6 hours of darkness.

Q.5 When do i use the superthrive and how much?

My reading here suggests that you don't use any nutes for the 1st 3 weeks. I'm on day 7 or so and no nutes yet.
