Twenty Eleven Post Width Problem

Hey,

So I’ve recently been experimenting with the Twenty Eleven theme, and while it’s simple and good, I have a few problems.

1. When I click on the post, it actually all goes to the middle and there’s a lot of space on the left. This is just testing words and images but you can see what happens – http://www.smashingcamera.com/2011/11/fujifilm-xs-1-bridge-superzoom-camera-announced/

There is so much unnecessary space on the left, I would like to have it removed so my post looks normal. I would also like the title to be higher, not lower than what it looks on the homepage.

If possible, I would also completely want to get rid of the comments and anything related to them.

Thank you so much to anyone that can help!
