calling all handypersons!

Unhandy guy here (voted in high school shop "Most Likely to Abuse a Tool). I have an 8x10 room(windowless) that I want to divide into two rooms.I also want to use a false wall a few feet in from door so I can use door to exit ducts into a hallway, while controlling light exposure to flowering section. I want to avoid putting any more holes in the ceiling or walls because its a nice room with textured surface and ceiling and I won't be able to fix 'em later. One person suggested using "Panda paper" but I can't seem to find it and don't know the best way to hang it. Whatever I use as false walls, I need some idiot instructions on how to construct it. If you want to add some suggestions about hanging ducting and mounting inline fans all the better. What about using some kind of racks/scaffolding. I've read all the tutes I could find but none describe the nuts and bolts of nuts and bolts. Thanks all.
