Find the class in style.css in your theme, and change the font there.

In the text box here, this takes care of it.

textarea#post_content {

font-family: arial, helvetica, sans-serif;

font-size:2.0em;

color: green;

}

You can also just find .postform textarea in the style.css and add your rules there. Either way seemed to work fine.
