It is not possible to tailor the links that Google displays under your search result. It just happens. Also the information in the page descriptions is again down to what Google thinks is the most relevant information to show based on your search results.
It won't always get it right. But there's not a lot that can be done, the last time I checked. The only exception to that is if there is any new functionality in Google Webmaster Tools that I'm not aware of.
