FYI, since Google now allows you to link directly to your profile with the rel="author" link I simply modified postbit_social1 to this for the google link:
HTML Code:
<vb:if condition="$social['google']">
<a target ="blank" href="{vb:raw social.google}"<vb:if condition="$post[postid] == $GLOBALS['qrfirstpostid']"> rel="author"</vb:if>><img src="http://images.nikonites.com/images/postbit_social/google.png" alt="Add {vb:raw post.username} on Google+" /></a>
</vb:if>
All this says is 'if first post, insert rel="author"'
