Once installed, the plugin will begin parsing your posts, bookmarks (AKA blogroll) and other content and looking for links.

Plugin: Simple Tags

If you tag your posts regularly, you may want to use Simple Tags, a WordPress plugin that extends post tagging features in WordPress. It helps you organize keywords, gives you hints on relevant keywords based on your post’s content (using free web services such as the Yahoo Term Extractions API), and allows you to batch-edit and batch-replace existing tags.

Plugin: Auto-hyperlink URLs

Automatically hyperlink text URLs and email addresses originally written only as plain text. This plugin seeks to replace and extend WordPress’s default auto-hyperlinking function.

Plugin: User Switching

User Switching allows admins to easily switch to another user, skipping the log-in-log-out process which can become quite lengthy when you’re testing a site. If your site has many different users than this is one plugin that is worth checking out.

MySQL database management tools:

For the WordPress developer, understanding the underlying MySQL tables and supporting data is a must. Popular hosting accounts such as Bluehost and HostGator provide myPhpAdmin to administer the database. However, I like the client-based tools for query execution and basic table changes.

Codex: Tools > Import Screen

Importing data into your WordPress blog is many times, necessary and useful. If you are moving from another host, or just to start your blog, then import data into your blog may be the answer.

You will need to install the WordPress Importer Plugin in order use this feature.
