any customizations you do via the theme options are stored in teh WordPress database in teh wp-options table. The only thing you might loose are any CODE changes you made to teh php modules that make up the theme.
The only other thing you need to do is make copies of any images you added to the atahualpa/images or atahualpa/images/header folders. Those images need to be copied to the new versions folder and if you referenced them directly in the theme options, you will need to change the reference. For example, if you used a background image and specified
you would have to change 'atahualpa' to 'atahualpa351'
Give a person a solution, you fix one issue, teach a person how to solve their problem you enable them forever.
