It appears like you haven't got very many incoming links to your site yet. Naturally I'm not an expert on optimizing your site, but I would guess that organic search engine traffic should be a major source for you.
For example, I tried googling "books barack obama has read", and you site didn't show up in the first few pages. If I were you, I'd be more concerned about the search engine ranking than optimizing a facebook fan page.
In short: find out ways to get relevant links pointing to your site.
It depends. If you google "books linus torvals reads" I am the second result. Bill gates favorite books , I am in the first page. But thanks I will work on this.
You should also do some keyword volume research (using adwords keyword tool for example). It will show you which keywords are popular, and then you can tailor your content in consequence.
You can also use the list google suggest gives you: if you start typing "books barack obama" the first reading result is "has read" and not "reads". Hence it suggests to me that you should optimize for "books barack obama has read" (meaning that should be the title of your page and your first H1 tag to start with).
