Honestly, the best FREE tools you can possibly find are in the SEO BOOK Blog.
Visit SEOBook by Clicking HereOn top of the blog page you will find a link to "tools" and there you will find an endless amount of tools you can use. His Keyword suggestion tool is phenomenal. It will show you Google and Yahoo results, as well as the amount of competing pages for keywords and how much it will cost to bid on keywords.
His book is also great. You can find the link to it on top of the blog page. The author also provides videos and other great SEO information. When Wordtracker was too expensive for me, I used this site for all my SEO needs.
Good Luck to you all.
