2. I guess you might be interested in run-this – there is a wordpress plugin to allow your readers to run your snippets in the browser.

3. For WP-Snippets, I use Prettify.

   You should probably use a plugin for escaping characters to be able to display code without having to do it yourself, or your code wont be displayed. Or just put this in functions.php in your theme folder to do this automatically:

   function bbcode( $attr, $content = null ) {
       $content = clean_pre($content); // Clean pre-tags
       return '<pre"><code>' .
               str_replace('<', '&lt;', $content) . // Escape < chars
               '</code></pre>';
   }
   add_shortcode('code', 'bbcode');
   

   And then wrap your code with [code]<?php echo 'hello world!'; ?>[/code]
