Use the WordPress function language_attributes() rather than manually specifying language
Use the charset stored by the site (should be utf-8 anyway)
Closing tag on meta element
Use wp_head() to provide everything else brought in by WordPress
Use wp_footer() to load anything provided by WordPress
Use WordPress provided jQuery, account for no-conflict mode

WordPress loads jQuery in no-conflict mode because `$` cannot always be relied on. Though this has become less important now that jQuery has effectively won the `$` namespace, it's still a good idea to account for it.

Ideally, the Javascript will rely on jQuery rather than $ in the final version.
