JQuery best practices
<p>Ok guys, three questions here. They are all pretty noobish, but I just want to get your guys' thoughts on them.</p>

<p><strong>1)</strong> When writing a jquery script, should I include type?</p>

<p>IE: </p>

<pre><code>&lt;script type="text/javascript" charset="utf-8"&gt;
  //Jquery here
&lt;/script&gt;
</code></pre>

<p>or is just an opening and closing script tag acceptable?</p>

<p><strong>2)</strong> I know it's a best practice to include all JQuery just before the closing body tag, but does this also mean I include the actual jquery.js file just before body as well?</p>

<p><strong>3)</strong> What if my page is reliant on jquery to look how it should (not just action events/ajax/etc). For example, I'm using a jquery plugin called datatables, which sorts through my specified database and automatically paginates/sorts/etc. I find that because I include all the scripts after the DOM loads, I see a raw format of the datatable until my datatables.js file and corresponding constructor loads. Would it be acceptable to include this before my body loads, so that this doesn't happen?</p>
