I don't know the first part, but I have done the second part, so I'll answer that...
Make custom NPCs/creatures for your enemies and use http://geck.gamesas.com/index.php/GetDeadCount on their Actor ID, once the value of GetDeadCount reaches a value that represents all of that type of NPC/creature, you can use http://cs.elderscrolls.com/constwiki/index.php/SetStage to advance the quest stage.
OR
What I did was have a script keep track of the number of a particular actor, if that number fell below a threshold, I would spawn another one. The actors all had a script running on them that decreased this value when they were killed in an OnDeath block.
