Last week I attended SearchFest from SEMpdx. It was an awesome day crammed full of all the search engine marketing and social media information my mind could handle.
One of my favorite presentations of the day was from Rand Fishkin of SEOmoz. He ran through a list of 50 tools to help solve your marketing problems. He's been generous enough to post the presentation, check it out on the SEOmoz website. Check it out, you'll find a ton of great information.
