For more details and flow, check out my WordPress Theme Directory slides from WordSesh 2012
Get a WordPress.org account if you don't have already.

Download the latest WordPress version
Set it up locally (install WordPress with a clean database)
Enable WP_DEBUG as true in wp-config.php in your WordPress folder
Download the Theme Unit Test data XML - https://wpcom-themes.svn.automattic.com/demo/theme-unit-test-data.xml
Go to your admin dashboard -> Tools -> Import -> WordPress, it would ask you to install the WordPress importer - install it and upload the XML

Your setup is ready to test then.

Get one assigned to you for a review from queues 4 up to 1
Install the theme in your WordPress setup
Do a complete WordPress review according to the guidelines
Test UI, code quality, even compatibility with some fancy plugins
Login to Trac with your WordPress.org username
Leave a comment in the theme ticket with your proposal - approved or not - and your review (list of violated guidelines or confirmation that everything is OK).
