For #1 the speedbar (if you are referring to your black banded horizontal navigational menu)
Find the table inside subnav which looks like this...
<td class="subnav"><table style="float: right;" cellpadding="0" cellspacing="0">
Then remove the style="float:right;"
so the table looks like...
<table cellpadding="0" cellspacing="0">
=======================
EDIT I left style="float: right;" in the table - not a very good example
