They stack additively. 20% + 10% = 130% threat generation. Exactly identical effects don't stack with themselves in DDO. I'd have to check to see how all of the items are set up - I think that we've set most of them up as unique effects.
I think that we currently have it set so threat reducers can't bring you below 50%, but I'll have to check.
Theat is mostly permanent. If you cease to be (died, left the dungeon, teleported), you'll drop off the threat list entirely. Monsters that teleport also clear their threat list, as do monsters that leash. Some monsters also have unique behaviors, or ignore the threat list entirely.
Aggro transfers when a monster re-evaluates its targets and someone else is at the top of the list. Monsters don't instantly switch targets when someone passes the previous top aggro target, they tend to stick to someone for several seconds unless someone forces reevaluation.
