Add a bigger number of posts after a specific number of posts

I am using the wordpress theme wptube premium and my site is imediazone.net. I would like to do the following: As you can see on my site 12 posts(video thumbs), what i want is after the 9 th post, when i add more posts to end the sidebar and let me add more posts ( another 2 would fit) after that.
My main index template is:

<?php

get_header();

$orderby = 'date_new';
$orderby = '&orderby=date';
if(isset($_GET['order']) && !empty($_GET['order']))
{
	$order = $_GET['order'];
	switch($order)
	{
		case 'date_old' :	$orderby = '&orderby=date&order=ASC';
			break;
		case 'rated' :	$orderby = '&r_sortby=highest_rated&r_orderby=desc';
			break;
		case 'viewed' :	$orderby = '&v_sortby=views&v_orderby=desc';
			break;
		case 'discussed' :	$orderby = '&orderby=comment_count';
				function comment_count_orderby( $orderby ) {
					return "comment_count DESC";
				}
				add_filter('posts_orderby', 'comment_count_orderby');
			break;
		default :	 $orderby = '&orderby=date';
			break;
	}
}
$order_url = get_option('home').'/?order=';
?>

AND my style.css is: http://www.imediazone.net/multimedia/themes/wptube/style.css.

Here is a screen shoot of what i want to do:

Don’t know where to get started i am a noob in php. And i know some css, but i declare myself still a noob.
Please do help me i will add reputation point.

I didn’t look at the code you posted, I am assuming if you tell WP to display 13+ thumbnails, they wrap to after the third column. If so, the div you have your side bar in is not inside the div that your videos are in. If you put a border on these, you will see this…

Thanks for the reply, i understand what you mean, but how to put a border? I mean the code is a bit complicated, don’t know exactly what to do.

Actually i changed my mind i want to add a module below those: Something like “Most viewed”, just that don’t know where to start.
Single thing i know is to add the header with the name “MOst viewed”, that i just added, don’t know how to add the content, wished to make the top 5 most viewed videos, all in a line.

How much of the code did you write, copy from elsewhere, and came from a source/theme you downloaded?

The theme is called wptube, it is a premium, i did not create it, i just want to modify it. Just that don’t know where to start. I only added the title on my index page for the module i want to add: “Most Viewed”.

Oh I see. To be honest that code is junk, and looks like it was thrown together. The code

 <div class="continue" alt="free music videos">

isn’t even valid code! It looks like the author is trying to “help” you and do SEO, but that wouldn’t do any good for you.

[]If you are using firefox, I would get firebug, and look at the code with that. Usually by default you can click on the page and it traces through code to where you clicked. If you use IE8+, you can hit f12, then ctrl+B within the devloper tools panel, and click like in firefox. If you use chrome, you can hit F11 or f12, which opens a firebug-like panel.
[
]Once you click, click the element in the next level of the heirarchy to ensure you are getting the whole part of that section, and take note of the class/id name.
[]Go into you css, find the noted class/id, add a border to it, to make sure thats it.
[
]Put the section within the div with the videos
[]Check flow and such
[
]Remove the border for the section, then (:[/list]
