You missed:

- Write compact efficient CSS (arguably the current CSS file is far too big)

- Combine all CSS files

- Don't use question marks in a resource URL (.css?v=234)

- Write valid compact efficient HTML (duplicate meta tags like: ICBM, unnecessary tags like Google verify, inline CSS, depricated HTML: align="left")

- Dont use spacer divs (div clear="all" style="padding-top: 5px") for a better render flow

- Delay loading javascript to the body of your site.

- Combine javascript files

- Compress javascript and CSS files.

- asynchronous loading of web fonts and analytics code.

- Load all CSS files before JS files.
