If you want the slider to appear on the front page then you will want to post the PHP in index.php for your theme. Don’t post it in a loop or your slider will appear everytime the loop is executed.
<?php get_header(); ?>
<div id="wrapper">
<div id="top"><?php get_smooth_slider(); ?></div>
<div id="content" class="home">
Lorem ipsum....
</div>
<?php get_sidebar(); ?>
</div>
<?php get_footer(); ?>
