#1 is not really my thing, someone else will have to help you out with that one.
#2 You can do the same thing you did with the JavaScript. Take the style code without the style tags and save it in a blank file with the suffix .css and then add this to the head section where you added the script link:
Code:
<script type="text/javascript" src="/js/jquery/jquery.pack.js"></script>
<script type="text/javascript" src="/js/jquery/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="/js/jquery/thisisthenewfile.js"></script>
<link type="text/css" rel="stylesheet" href="folderwithcssfile/cssfile.css" />
