S2Bloggish

Hi. I am new to Insane Journal, the Bloggish Layout, working with CSS code and I have a free account. On my journal I am using a code found here  http://asylums.insanejournal.com/freelayouts/2957.html#cutid1 (the hyberlink button isn't working for some reason for me). I can't seem to find the part of the code that changes the colors in the side bar nor can I figure out how to add links. Any help would be greatly appreciated.
