Man, I hate deadbeat stackoverflow users. But a useful question (and answer) I think: http://stackoverflow.com/questions/5923388/displaying-wordpress-page-number-count-in-relation-to-siblings

Here’s a quick recipe for use on child pages. Works in your sidebar or template. This tells you that you are on page X of Y out of the child pages of a particular parent.

To be used on a category/archive page in WordPress. Outputs all the tags used in all the posts in the category.

<?php
	// get the category ID of whatever category we are looking at the archives of
	$category_id = get_query_var('cat');
	// get the ids of all the posts in the cat
	$post_ids = get_objects_in_term( $category_id, 'category' );
	// get all the tags from these posts
	$tag_ids = wp_get_object_terms( (array) $post_ids, 'post_tag', array('fields' => 'ids') );
	$tag_param = '';
	if ( ! empty($tag_ids) ) {
	//change 'include=' to 'exclude=' to achieve the opposite..
	$tag_param = 'include=' . implode(',', (array) $tag_ids );
	}
	//format the output using wp_tag_cloud parameters see:
	//http://codex.wordpress.org/Function_Reference/wp_tag_cloud#Parameters
	wp_tag_cloud('count=0&order=RAND&smallest=8&largest=22&'.$tag_param); // don't forget to tack on your includes
	?>

Note that you can also pass this to get_tags(), which you can use to roll your own list of links. For instance, I recently did something like:

	$tags = get_tags('orderby=count&order=DESC&'.$tag_param); //beware params are not all the same
	$html = '<div id="port-tags">';
	foreach ($tags as $tag){
		$tag_link = get_tag_link($tag->term_id);

		$html .= "<a href='{$tag_link}' title='{$tag->name} tag' class='{$tag->slug}' data-filter='.tag-{$tag->slug}'>";
		$html .= "{$tag->name}</a>";
	}
	$html .= '</div>';
	echo $html;
