Drupal6 Zen Sub Theme Help

It seems that the best approach for a sub theme is to start with the Zen theme. I have a need for some basic changes to create a 3 column with minor header changes, new to Druoal so I would like an overview on the approach and the changes needed.

Just Modify Zen

I would just take Zen, copy it to a new folder and update the .info file and modify the css and .tpl files as you go rather than creating a sub-theme.

The book Drupal 6 Themes from Packt Publishing has a whole chapter on modifying an existing theme (Zen). And it has tons of other great examples for theming.
