Here is my recommendation: focus on quality and diversity.
1. Build high quality backlinks from different platforms such as web 2.0's, high pr comments, profiles, article directories, social bookmarks, wikis etc.
2. Diversify your anchor text: use your money keywords <40% of a time (this varies based on opinions) and in addition use generic terms such as "click here" "this site" with your URL "www.site.com" "http://site.com"
3. Drip feed your backlinks: you want to be consistent with building your backlinks.
4. Add social signals: facebook, twitter, google + etc.
Hope that helps.
