3 column Site - needs to be SEO Friendly

I have a 3 column site and am still new at site building. I want to modify my current css page so that my main content (currently coulmn 2) will display first to the Spiders. (column 2-1-3).

I have read that this is good seo, so that google will get the most important content first. True? Does anyone have any help they can give me to complete this task?

Thanks

 

<div id="wrapper">
  <div id="major box"> <!--holds central and left sidebar, float it left-->
    <div id="content">
      <p>This is the main content box, float it right</p>
    </div>

    <div id="nav-sidebar">
      <p>This is the left column</p>
    </div>
  </div>

  <div id="other-sidebar">
    <p>This is the far right column.</p>
  </div>
</div>

Code (markup):

cheers,
