Can’t change right sidebar

hello again from http://www.weightlosswinnow.com

So now I am trying to change my right sidebar. Since I bought this theme (Lifestyle), the right sidebar looks dynamic. If I go to Admin panel and look at the widgets section, nothing is populated as active. I just have an Available Widgets section and then an Inactive section. If you look at my website however, there are items in the right sidebar so I’m assuming they are dynamic. I want to make this sidebar into items of my choice so I want to pull from the admin options in WP. Currently in my right_sidebar.php (I’m assuming I would have to do something in this area). How do I customize the sidebar to pull whatever I want there (say a poll or anything else, just so long as it’s whatever I want? Please when replying be as specific and simple as possible since I am not good at CSS. I’m trying to learn, but not too easy for me. Thank you so much for your help. I have the following in sidebar_right.php:

<div id=”r_sidebar”>

<ul id=”r_sidebarwidgeted”>

<?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(‘Sidebar Bottom Right’) ) : ?>

<li id=”links” class=”widget”>
<h4><?php _e(“Blogroll”, ‘studiopress’); ?></h4>

<?php wp_list_bookmarks(‘title_li=&categorize=0’); ?>

<li id=”meta” class=”widget”>
<h4><?php _e(“Admin”, ‘studiopress’); ?></h4>

<?php wp_register(); ?>
• <?php wp_loginout(); ?>
• WordPress

<?php wp_meta(); ?>

• XHTML

<?php endif; ?>

</div>
