Page load partially optimized

This is a screenshot of the Net tab in FireBug in FireFox 3.6. It displays a sequence of downloads for a page on this web site.

1. The first request downloads the HTML file.
2. The second and third requests receive minified CSS files linked in the head of the HTML file.
3. The fourth request downloads minified JavaScript file linked in the head.
4. Afterward, multiple images are downloaded. First, images referenced by the HTML document (e.g. the logo) and then images referenced by CSS files. Those images are not sprited (room for improvement).
5. Towards the end, Google Analytics files are received and JavaScript code executed.
6. The last two images are downloaded by JavaScript.
