I would recommened just using Disqus, because to get WordPress comments to work on non WP pages will require serious hacking wordpress core, or you can say in that hacking, we will almost create a new Standalone Comment system. So would recommend go on using Disqus

Yes, you can show recent posts instead of featured posts, please provide the theme or plugin, you are using, then we can give you the exact solution to it.

Check the Other Tab in the “Titles & Meta”, you will find your answer their.

If you do not want to use plugin, then refer to this post.
it walks you through creating multiple excerpts. (I don’t really understand whether you really want it :P)

but i personally use <!–more–> tag instead of excerpts has it keeps the layout nice and clean and also keeps the post formatting in the way author wanted it.

Search for twentyfourteen_wp_title function in functions.php .

function twentyfourteen_wp_title( $title, $sep ) {
	global $paged, $page;

	if ( is_feed() ) {
		return $title;
	}

	// Add the site name.
	$title .= get_bloginfo( 'name', 'display' );

	// Add the site description for the home/front page.
	$site_description = get_bloginfo( 'description', 'display' );
	if ( $site_description && ( is_home() || is_front_page() ) ) {
		$title = "$title $sep $site_description";
	}

	// Add a page number if necessary.
	if ( $paged >= 2 || $page >= 2 ) {
		$title = "$title $sep " . sprintf( __( 'Page %s', 'twentyfourteen' ), max( $paged, $page ) );
	}

	return $title;
}

remove this line $title .= get_bloginfo( 'name', 'display' ); and it will remove your blog title.

Only use this solution if you do not want to use any plugins and also note that once the theme is updated, you will have to again apply this fix.

Yes, Changing permalinks reset’s your Facebook likes, because Facebook likes count is based on a Specific URL share/like.
