Our own patio11 has written quite a bit about SEO, especially SEO with little budget; start at http://www.kalzumeus.com/2010/01/24/startup-seo/ http://www.kalzumeus.com/2010/01/24/startup-seo/ and go on to the greatest hits (key ideas: scalable content generation, long tail keywords). Also note Patrick's love of A/B testing. There are, of course, many more general SEO resources; I think seomoz.org is mentioned often. Note that you're getting advice that people I trust trust, I'm not exactly an expert.
