The 3 column template has no header, since the blog title is part of the main background, and below the heading you can add a one line description. Momochi's main column has a welcome message box on top with a cartoon character, you can use that box for daily quotes or any other feature.
Then the post starts with the date stamp on top and author name, time and comments appearing below the post. The two sidebars appear on either side of the template, both are similarly designed. You can have blog archives, recent posts or comments on the left, while the right sidebar can be used for about me, labels or any other widget you like to add.
The pink and white font colours goes well with the template theme, and yes its a girly theme. You can use it for your personal blog, random ramblings etc.
