QANDA Layout - where to begin?

Hi,
My QANDA page looks very unprofessional. How do I change the layout and is this really the default layout?
Can't edit the layout using UpFront - is CSS coding the only way?
My site: http://skilsmisseforum.dk/questions/
What I want it to look like: http://pumenbaike.com/questions/
How do I get started? Widgets, sidebars, categories etc.
A very basic question - hope it's not a stupid one :wink:
Thanks in advance :slight_smile:
