Someone PLEASE help me with adding a jquery script to WordPress

btw It seems that the info in the search results only brings forth outdated information. Nowhere is there any info on adding this to the latest 3.2.1 version of WordPress.

1) How do I call the jquery (wp_enqueue_script)
Put this in your functions.php file and reference files accordingly

function my_init() {
	if (!is_admin()) {
		wp_deregister_script('jquery');
		wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js', false, '1.3.2', true);
		wp_enqueue_script('jquery');

		// load a JS file from my theme: js/theme.js
		wp_enqueue_script('my_script', get_bloginfo('template_url') . '/js/theme.js', array('jquery'), '1.0', true);
	}
}
add_action('init', 'my_init');

3) CSS – do I simply append the css from the script to my style.css file?
yes. create a css file in your script folder specific to the script and reference it accordingly
I reference my style sheet via import from my global stylesheet
@import url('../jscript/css/style.css');

5) How do I incorporate the html?
Directly into the page or where you are needing the script.

Moderator Note: Please note that it is never a good idea to deregister jquery as it can break core WordPress or plugin(s)
