Quick answers: Yes, keyclone is 1 license per box. It's so unbelievably worth the $$ though. (I am not a paid spokesperson, just a huge fan) For collection quests, what I do is set loot to FFA and get all the items for character #1, then use my focus macros to set the new "main" to character #2 and loot the drops, etc. You can also just run slightly past the corpses on your main and quickly switch over to the secondary accounts to loot. (run past so that those on /follow can loot without additional movement).
