There is an addon that will allow the main to share quests and the alts to auto accept them without having to click. Also escort quests, party invites, and rezzes will be auto accepted. I cant remember the name of the addon but it is listed in the wiki under software.

*sorry reread the OP - was in a hurry and didnt catch the part about looting lol. So far to loot effectively on alts you gotta alt-tab. *
