I would imagine you could just move your closing 'if' to after those.
i.e.:

<if condition="$show['member']">                             
                <div>$post[icqicon] $post[aimicon] $post[msnicon] $post[yahooicon] $post[skypeicon]
<!-- Myspace start -->
<if condition="$post[field6]"><a href="http://www.myspace.com/$post[field6]" alt="View my myspace" target="_blank">
<img src="images/misc/im_myspace.gif" border="0"></a>
</if>
<!-- Myspace end -->
<!-- Facebook start -->
<if condition="$post[field8]"><a href="http://www.facebook.com/profile.php?id=$post[field8]" alt="Go to my Facebook" target="_blank">
<img src="images/misc/facebook.gif" border="0"></a>
</if>
<!-- Facebook end -->
<!-- Twitter start -->
<if condition="$post[field7]"><a href="http://www.twitter.com/$post[field7]" alt="Go to my Twitter" target="_blank">
<img src="images/misc/twitter.gif" border="0"></a>
</if>
<! --Twitter end -->
</div></if>
