Can I reference APA style?

How do I cite in text a book with multiple authors? For example Jim Smith, Jan Jones and Will Rogers wrote a book published in 2010:

• First time: Smith, Jones & Rogers (2010) Then: Smith et al. (2010)
• First time: Smith, J. et al. (2010) Then: The same way, there is no difference.
• First time: Smith, J., Jones, J., and Rogers, W. (2010) Then: Smith, J. et al. (2010)
