How to add H1 titles for the middle & right column (on 3 column layout)

Here’s my blog;

The blog is set up in 3 colums

-Left: Posts
-Middle: Photo Gallery
-Right: Movies Clips Gallery

Notice the H1 title on the left gives the reader an idea of what they are looking at? Well I want to ad the same thing for the right & middle.

-Middle: “Latest Photos”
-Right: “Video Clips”

In my Stylesheet here’s the code where I think i need to work with

/********************************************
Latest stories on the left
********************************************/
.latest_stories h1 {
   font-size: 2em;
   letter-spacing: -1px;
   color: #f5006e;
}

.latest_stories h2 {
   font-size: 1.8em;
   margin: 0 0 10px 0;
}
.latest_stories h2 a {color: #000}
.latest_stories h2 a:hover {text-decoration:underline}

.latest_stories .last_date {
   display: block;
   line-height: 2.2em;
   font-family: georgia;
   font-style: italic;
   color: #666;
   border-bottom: 1px dotted #ddd;
}

And on the home.php template

<!-- start left column -->
<div id="leftcolumn">
<div class="latest_stories">

<h1><?php print LATEST_STORIES; ?></h1>
<span class="last_date"><?php the_time('F d, Y'); ?></span>

Im guessing I just need to pretty much copy the same type of code for the middle & right class?

Middle (home.php)

/<!-- start middle column -->

<div id="middlecolumn">
<div class="latest_stories">

<h1><?php print LATEST_STORIES; ?></h1>
<span class="last_date"><?php the_time('F d, Y'); ?></span>

Middle (stylesheet.css)

/********************************************
Photos column in the middle
********************************************/
.latest_stories h1 {
	font-size: 2em;
	letter-spacing: -1px;
	color: #f5006e;
}

.latest_stories h2 {
	font-size: 1.8em;
	margin: 0 0 10px 0;
}
.latest_stories h2 a {color: #000}
.latest_stories h2 a:hover {text-decoration:underline}
