Ok, so I found this theme, which you should be able to see on my forum. I love this theme or at least how the body looks, and I want to change the back ground and logo banner. I already changed the background. Anyway, something with this theme messes with my side peekaboo box. I found out that if I have the size at 100% for the theme, the box shows up but the forum looks horrible. Is there any way to fix the theme with out changing the appearance to where it wont mess with the box? Or if you could, tell me how I can make a completely new theme but still have the body looking like that?

In your stylesheet, find this line:

#wrapper {width: @wrapper_width; margin:0 auto; overflow-x:hidden;}

And remove the red part. You can also adjust the width of the forum normally now, by editing the variable @wrapper_width;
