How to edit sidebar?

[tahbikat]

Sooo I'm a little confused on how to edit the sidebar's structure I guess you could call it.

On my site when I first made it, I edited the sidebar to display as a horizontal bar under the menu bar instead of a sidebar. However, I don't exactly know where to go to pretty it up.

I know how to input the php code for it, but where do I do this? I only want a user's name, money, messages, and users online to display horizontally.

See mysgardia.com to see what I'm talking about. Right now the bar is big and bulky. I want to make it thinner and have the fields currently there to only be shown. Can anyone help? :c

EDIT: I've looked in the template.tpl file and see that the code for it is <tr><td>{$sidebar}</td></tr>. Uhh what's that? Haha.
