Damon put up .261/.326/.418 in 2011 and is projected to give similar production in 2012. He has a great reputation as a clubhouse guy and would probably be a good influence on the younger guys on the team and provide some leadership on a team that often lacks it.
Ibanez looks even better, his slash in 2011 was .245/.289/.419, which is low for him but good for his age. However his Bill James projection for 2012 is .260/.325/.431 with 17 homeruns (based on 505 PA). Frankly these are about as good numbers as you can ask for from a bench guy. To be honest even at his age, I might start him over Bay. They had fairly similar numbers last year except Ibanez outpaced Bay in SLG and HR. Their 2012 projections are similar but frankly I have more faith in Raul producing than Jay Bay.
