Content Type Layout for Users
You could use Display Suite to create custom layouts of your forms and content displays. 


  Display Suite allows you to take full control over how your content is displayed using a drag and drop interface. Arrange your nodes, views, comments, user data etc. the way you want without having to work your way through dozens of template files. A predefined list of layouts (D7 only) is available for even more drag and drop fun!


A combination of Display Suite and css will allow you to really tweak the standard layout of your theme. 

Otherwise Panels is another module that allows you to customize the layout, among many other features.
