Manage Wordpress theme options in a multi-dimensional array

Hi,

Can anyone offer any links to tutorials on managing wordpress theme options which are stored in a serialized multidimensional array?

For example, below is a snippet of an array which contains the settings for my wordpress theme;

$settings = array(
            /* heading */
            'typography_heading' => array(
                'font-family' => 'Open+Sans:300,300italic,regular,italic,600,600italic,700,700italic,800,800italic',
                'font-size' => 20,
                'font-style' => '',
                'text-transform' => '',
                'line-height' => '',
                'letter-spacing' => ''
            ),

What would be the best, correct, way to manage these options?

Cheers
