I won't analyze this trade because many of the brethren above me already did that.
I would do it. You get Pap (who I am not a fan of, but he is pitching in a contract year, so he'll prolly pitch his nuts off), Zimm (all of these abdominal injuries are worrying me.) He prolly won't be back for about 2 weeks, but once he does get back, everybody's production will go up in that lineup.
Granderson will beat his last year's stats and he's a good sub for Ethier , especially @ Yankee Stadium.
