There is a mod called QuestHelper that can track the progress of everyone in your party (provided they all have the mod of course). It can also tell you where to go to accomplish all your objectives and plan the fastest route for you to take. I was quite happy to discover it from another thread here on the boards. http://wow.curse.com/downloads/details/9924/ I'm not sure if it can send a message to party chat with the progress as you mentioned, but it puts waypoints on your map for any unfinished objectives or quests needing to be turned in of everyone in your party, and the waypoints will have a tooltip with the progress of each member who hasn't completed the quest. Pretty much accomplishes the same thing.
