I use two seperate acceptall macros (if I put them together on one button I'll teleport out every time I try to trade while in an instance! bad!)

/run AcceptResurrect();
/run StaticPopup_Hide("QUEST_ACCEPT");
/run ConfirmReadyCheck(1);
/run AcceptGroup();
/run AcceptQuest();
/run AcceptTrade();
/run RetrieveCorpse();
/run RepopMe();
/run ConfirmAcceptQuest();

releases when you die, trades, can accept rezzes and quests (although thats generally handled by jamba) and then for LFG

/click LFDRoleCheckPopupAcceptButton
/click LFDDungeonReadyDialogEnterDungeonButton
/run LFGTeleport(IsInLFGDungeon())
