To list only the pages you want, go to Appearance -> Menus. There you can create and set a custom menu that will replace the list of all pages on the left.
As for hiding the left column completely, there is no way to do that through theme configuration. You would need to modify the theme’s files.
Thanks
I have found the code to delete the left column and the place in the css file to widen the post area.
