The second thing you call, i don't have an answer to. It has to be in the footer part, but i don't played with it yet (will do soon, cause i don't like it the way it is now either).
But the first thing I can help you with.
Go to you admin panel, go to the skin manager. Choose transparencity and choose all style options. Then find the header box (in top of your screen) And outcomment the whole part between:
<!-- logo --> and <!-- /logo -->
With <!-- at the begin and --> at the end.
So it looks like this:
PHP Code:
<!--
<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>
<td align="$stylevar[left]"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
<td align="$stylevar[right]" id="header_right_cell">
<if condition="$ad_location['ad_header_logo']">$ad_location[ad_header_logo]<else /> </if>
</td>
</tr>
</table>
<div class="logo">
</div>
<!-- /logo -->
-->
Hope you can find it.
