Help with New York 1.0.1

I am new to building my own wordpress blog and need help setting it up. I have activated the theme ‘New York 1.0.1’ and can’t seem to get it looking the way I want. It looks nothing like the snapshot given for the theme. I would like to format it and set the colors similar to the what the snapshot looks like.

How do I set up my blog to look similar to the example like this—

Thanks.
