I need help here ppl

Okay so I'm an old pro when it comes to layouts, etc on Myspace....but I am new to this blogger setup. I don't like my layout or background but when I went to change the html....it got all jacked up. I usually am the one ppl go to for technical assistance....I'm the computer nerd of my family. But here....I'm stumped! I want a page that shows my personality and while pink is one of my favorite colors; my page is blah! HELP!
