need help with theme (fix a few things)

Sorry about the title, couldn't better describe it. :P
But I recently installed WP to my site, and am now attempting to make a theme.
This is what I have so far : http://misconception.donemyway.com/
but I really want it to look like this : http://i50.tinypic.com/ws1fnm.jpg
what steps should I take to transform it into that?
Oh, and I am using the Default WP theme template, if I am not allowed to do that, please let me know. D:

Thanks!
