If you are new to JSF (and Ajax) I would recommend that you pick up one of many great books available that are focusing on teaching you the basics/foundation of JSF respectively Ajax.
JSF in Action, Manning
JavaServer Faces, O'Reilly
Foundations of Ajax, Apress
Ajax
Patterns, Apress
Ajax in Action, Manning
When you are comfortable with these two technologies/techniques the next good volume in your collection would be our book
