Search Engine Optimization - SEO

Tweet

I have reacently finished my site (still having some little details to work out) , and i read some SEO books. They say you need a high PageRank (PR) to rank good in google. So , my concern is: What does my site need(except for the Title - i`m modifying it now) but keywords (are they good?) , description (can anyone suggest a good one?) what other keywords should i use (body - header) and what other seo's can i make? my site is: http://www.hotduels.com Thanks in advance...
