Ok, get the floro as close as you can to the top of the plant and keep the other one off to side. To tell you the truth, it's probably just adding heat. I dont think that light fixture will hold the right kinda bulb. Go to home depot or some place like that and get a two way light bulb fixture. it holds two lights in one socket.
A computer fan will work just fine.... you might need two. just hook em up to a ac/dc converter. as for setting up the scrog just get some wood to make a frame that will fit inside your box and staple some plastic netting over the top of your plant. make sure your plant is about 6-8 inches tall then top it and it will grow bushy. i'd do this before putting the net over. Then bend the new growth through the holes in the net. hope this makes sense. -The house
