This inserts at the end of your post, links to other posts on your site that are similar in content to the current one. Its not to bad at all, I would like a bit more customisation options but, out of all the ones I have tried, this seems to be the best.
Google XML Sitemaps
This plugin generates a XML sitemap and submits it to search engines. It has a wide range of options and does exactly what it says on the side of the tin. Handy to use in conjunction with google webmaster tools.
SI CAPTCHA Anti-Spam
I only have this activated on my drawing site at the moment as that has been hit a few times by spam comment attacks. Again, It does what it says on the side of the tin, I have not had any spam comments since.
This allows you to set up 301 redirects on your site with ease, most recommended if you are planning to move from blogger to wordpress on the same domain.

Allows you, very easily to set up a contact form on either a page or post on a wordpress blog. A good few options of customisation
