I compromised doing these modifications. It takes out lines, grey background and Search.
Code:
<table cellpadding="0" cellspacing="0" width="100%">
{if $main ne "fast_lane_checkout"}
<tr>
<td height="22">
{*
{if $usertype eq "C"}
{ include file="customer/search.tpl" }
{/if}
*}
</td>
<td align="right">
{if ($usertype eq "C" || $usertype eq "B") && $all_languages_cnt gt 1}
<form action="home.php" method="get" name="sl_form">
<input type="hidden" name="redirect" value="{$smarty.server.PHP_SELF}?{$smarty.server.QUERY_STRING|amp}" />
<table cellpadding="0" cellspacing="0">
<tr>
<td style="padding-right: 5px;"><b>{$lng.lbl_select_language}:</b></td>
<td><select name="sl" onchange="javascript: this.form.submit();">
{section name=ai loop=$all_languages}
<option value="{$all_languages[ai].code}"{if $store_language eq $all_languages[ai].code} selected="selected"{/if}>{$all_languages[ai].language}</option>
{/section}
</select></td>
</tr>
</table>
</form>
{else}
{/if}
</td>

{else}
