How do you make the font size smaller in the Sidebox so it takes up less space. I'm trying to limit the size the sidebox takes up to the right of the text.

You could use
<div style="font-size:90%">...</div>
If you mean the sidebar, depends on what skin.
in Vector, something like the following in MediaWiki:Vector.css
#mw-panel { width: 9em !important; font-size: 90%; }
#content { margin-left: 10em !important; }
This is a bit untested, and might break when changing versions. Use at your own risk.
