Nothing new from Gorkfu's list ... I think you should look for your requirements first and then search for plugins.
Installing unnecessary plugins will make your website slow, and look clamsy.
I use Google XML sitemaps, All in One SEO pack, Add Lightbox, WassUp, Popular posts, Wordpress.com Stats etc plugins in different websites.
I just made my own little plugin today, kind of. It basically just grabs whatever I put in the post_excerpt, and then displays the page description meta. No excerpt, no meta.
well what I can suggest is the all in one seo.
I too vouch for All In One SEO
