Plugin 1: WYSI-Wordpress Plugin - Adds a WYSIWYG Editor
This plugin adds a WYSIWYG editor to the advanced editing screen of Wordpress, allowing you to edit posts as you would in any word processor application. It also includes an image uploader and manager. I personally find this plugin outstanding and it helps tremendously with your editing.
