Much better dude, hang all lights vertically over the plants as you have done dont wall mount (wastes light). I have pulled two ounce of 4x22 watt flouros before so dont worry about small veg plants. Under these veg till 12 inches whilst topping then lst and will give you a bit of time to get more lights for flower.
Glad to see you ditched those small puny cfl's and went with some propper lights. Notice how much brighter they are, rather have 20watts flourescent strip than 20watts cfl, imagine 2x20watt cfl compared to 1x40watt flouro.
Saying that change the flouro bulbs every 6 to 12 months for max eficiency. Plus get a small fan, flouros give off a little heat so you want some circulation at the least. I have my T5's about 7/8 inches from the plant and about right with a small pc fan, your t8's should go to about 4/6 inches at max from the plant tops if healthy but work it down to this.
I use cfl's and they suck dude, no way that cfl equivelant of 75watts is the same brightness as these two 40watt flouros.
