To add the small logos to the header on the right, you'll have to edit the header.php and style.css files. Let's start with header.php.
Right around line 60 you'll find this:
<div id="textlogo">
<h1 id="branding"><a href="<?php echo get_option('home'); ?>/" title="Home" ><?php bloginfo('name'); ?></a></h1>
</div>
<?php endif; ?>
Immediately following that is where you want to add your code for the logos. For example:
<div id="headerlogos">
<img src="thepathtoyourfirstimage.jpg" alt="alternative text" />
<img src="thepathtoyoursecondimage.jpg" alt="alternative text" />
</div>
Replace the "thepathtoyour..." with the path to your logo file. Next, replace the alternate text with your own.
Now go to your style.css file and add this (it doesn't really matter where you put it, as long as it's below the theme info at the top of the file).
#headerlogos{float:right;}
#headerlogos img{float:left; padding:0xp 10px;}
You can play around with the padding. The first number controls how much space is above and below the image and the second number controls how much space to the left and right.
That's a pretty general overview of what you'll need to do. Let us know if you need any other specifics.
