Disqus Comments Cut Off (and others)

Hi there,
Pretty happy with this theme so far but had one issue with Disqus comments:

1. Disqus comments interface is unable to load properly and is cut off. Disqus support has informed me that the interface will automatically fill 100% of the parent element in which it has been placed – in other words, they say the problem is with the theme I am using. Any thoughts here?

At the end of my header transition, my browser shows this:
// <![CDATA[ var disqus_shortname = ‘drive4corners’; (function () { var nodes = document.getElementsByTagName(‘span’); for (var i = 0, url; i < nodes.length; i++) { if (nodes[i].className.indexOf(‘dsq-postid’) != -1) { nodes[i].parentNode.setAttribute(‘data-disqus-identifier’, nodes[i].getAttribute(‘rel’)); url = nodes[i].parentNode.href.split(‘#’, 1); if (url.length == 1) { url = url[0]; } else { url = url[1]; } nodes[i].parentNode.href = url + ‘#disqus_thread’; } } var s = document.createElement(‘script’); s.async = true; s.type = ‘text/javascript’; s.src = ‘//’ + ‘disqus.com/forums/’ + disqus_shortname + ‘/count.js’; (document.getElementsByTagName(‘HEAD’)[0] || document.getElementsByTagName(‘BODY’)[0]).appendChild(s); }()); //]]>
? ?

Also,
2.Tags: Is there any way that tags are not shown on the main blog feed? I want tags to be used as a way to find related content, however with the amount of content I will be adding, there ill be too many tags, and it only adds clutter to the clean/ finished look.

3.Widget Text Size: Some of the Widget Titles are too large for my liking. Where I can change the class and make this font slightly smaller?
