comment styling

Hi I have a few questions regarding comment styling.

1. how do i get rid of this text `”You may use these HTML tags and attributes: <a href=”” title=””> <abbr title=””> <acronym title=””> <b>
<blockquote cite=””> <cite> <del datetime=""> <em> <i> <q cite=""> <strike> <strong>"

[Please post code or markup snippets between backticks or use the code button.]

2. How do i get rid of the text “comment” on the side of the input box?
