Hmm...well let me see if I can explain how to customize your profile. By the looks of it, you started already. You have to click on customize profile, I'm not sure if you can access it on the upper bar but I always click on my own profile (by clicking on user name) and on little bar under your avatar you can see the options "send message", "User Lists" and "Customize Profile". Once you click on that you can change the colors to your page. To add the picture in the background you need to upload it to an album and from them copy and past the "url" code into the section you want it to appear. I hope this makes sense so far...just play with it for a bit and you'll see what I mean. To add pictures/graphics you need to upload them or for example, the graphics I use I get from a site and just copy the code for message boards. Hope that helps.
