the red spectrum or fall sun is not needed to flower. what is needed is the amount of darkness to cause a plant to flower. 12+ hours of solid darkness.

everything else you said sounded good thought!

you can put the t-5s pretty much on your plants and they won't burn. they have much more surface area than a CFL so they don't get as hot to the touch. so just get them as close as you can.

a good rule of thumb is to keep your hand on top of the plants and lower your light, when after ~5 seconds you can't keep your hand their any longer due to heat then back up the light just a bit.

good growin!
