Help with Vertigo

In a nutshell, I'm looking for a code snippet to allow me to display content in the center of the page, or alternatively as it is but with more horizontal room, on pages where I do not display blocks, in the Vertigo Theme.

It seems clear the theme is designed for sites where both (right and left) blocks appear all the time. When blocks are turned off for a given page, two horizontal lines, side-by side, appear on the right where the blocks would normally show up as if waiting for blocks to appear. The content on the page gets squished over to the left.

For pages where I show blocks, everything is exactly as I want it. For pages where I don't want blocks, I'd much prefer to have node content show up in the center of the page instead or alternatively, to give the content more horizontal room and hide the horizontal bars.

My theme dev skills are pretty minimal and I really don't know where I would start, so I'd love detailed input on how to modify the theme to support my requirement. Earlier, I cross-posted this here, but the author of the theme may be traveling at the moment, and lately my luck getting quick responses for issues has been iffy.
