In answer to your previous question, yep, that would be in place of painting. Here's a pic of my veg room, and my flower room (while it was being prepared). You can see the e-blankets on the walls. Really shouldn't need anything else, just attatch right to the walls. Each one is like 5'x7.5'.
Great find on the CFL's! A couple pics of my CFL racks for you too, once you get past a few it's a bit easier to set up this way. Your choice, of course. I have mine 12 to a rack, jumper wires in between, and one plug. Used a piece of cardboard wrapped in the e-blankets (again, lol) for my reflectors.
