One important aspect that I failed to mention above with the static pages is duplicate content. If you are generating static pages from your dynamic pages, then you need to make sure that your dynamic pages are Disallowed in your robots.txt file. This will prevent duplicate content issues. Google and other SEs are getting better at indexing URIs with variables in the string.
