On your homepage, there is a button that says Colors + Styles. This will allow you to change your background. From there, you have the option of using one of the pre fab backgrounds that CafeMom offers, or you can upload your own.
For pictures, there is a widget on your homepage that is called Photos. Click on the Add a Photo button, and it'll walk you through uploading a picture.
For anything else, you might want to check out the CafeMom Newcomers Group, which is always full of people who can answer questions (it's a bit more instant gratification than Answers).
