Sidebar and css

I can’t seem to determine how to style my categories and post listing in my sidebar.

I want the lists to look the same for both posts and pages. currently the pages are intented but the categories are not. I’d like to eliminate the spacing between categories and have them appear more like the page listings. As well, in IE, the category, “Teacher’s Corner” does not appear???
Also the heading for my calendar does not appear in IE, only in Firefox.

Here’s the sidebar code:

<div id=”sidebar”>

• Home<img src=”<?php bloginfo(‘stylesheet_directory’); ?>/images/h2.gif” class=”righth2img” alt=”h2″ /></h2>
• <h2><?php _e(‘Pages’); ?>
  <img src=”<?php bloginfo(‘stylesheet_directory’); ?>/images/h2.gif” class=”righth2img” alt=”h2″ /></h2>

<?php wp_list_pages(‘exclude=25,89,90,91,92,93,94,95,96,97,98,99,18,7,8,9,10&title_li=<h2></h2>’ ); ?>

• <h2><?php _e(‘Categories’); ?>
  <img src=”<?php bloginfo(‘stylesheet_directory’); ?>/images/h2.gif” class=”righth2img” alt=”h2″ /></h2>

<?php wp_list_cats(‘exclude=5,7,8,9’); ?>

• <h2>Calendar</h2>
  <img src=”<?php bloginfo(‘stylesheet_directory’); ?>/images/h2.gif” class=”righth2img” alt=”h2″ /></h2>

<?php ec3_get_calendar(); ?>

• <?php _e(‘Events’); ?>
  <?php ec3_get_events(5); ?>
