Now you already have WordPress and Akismet activated, lets focus on the TEMPLATE you have downloaded from FREE WORDPRESS TEMPLATES. I actually recommend that you download 3 or 4 templates as sometimes they don't are not as nice as they appeared to be.

In case you are wondering, you will need to upload the templates to this place: wp-content/themes/TEMPLATE_NAME

After you have uploaded all the new TEMPLATES you will need to CHMOD the files to 666 or 777 in order to be able to edit them from the admin area (wp-admin/theme-editor.php - Design->Theme Editor). Two important things in the templates are:
<?php bloginfo('name'); ?> - this is the code to "call" TITLE of the BLOG
<?php bloginfo('description'); ?> - this is the code to "call" DESCRIPTION of the BLOG
that info can be changed on this page: wp-admin/options-general.php (Settings)

Adjust any thing you need on your template on the THEME EDITOR, but note that you will need to know HTML and basic PHP to do it! I generally change the BEGGINING of the HEADER of the templates I download to something similar to this:
<title><?php bloginfo('name'); ?> <?php wp_title(); ?></title>
<meta name="description" content="<?php bloginfo('name'); ?> - <?php bloginfo('description'); ?> - <?php wp_title(); ?>"/>
<meta name="keywords" content="LOTS OF KEYWORDS, <?php bloginfo('name'); ?>, <?php wp_title(); ?>"/>
