As Ruvanal said, most of the percent-based modifiers stack linearly - attack speed, model size, etc. The only exception that I am aware of is % damage modifiers - they multiply instead of stacking linearly. It's hard to find a lot of examples since Blizzard likes to use +flat bonuses instead of percentages. And as Ruvanal mentioned, some spells are exclusive to each other as well.
But anyway, I would tend to agree here with Ruvanal that they stack linearly, as the majority does.
The only caveat here is that there might be a lower-end cap on the threat reduction, perhaps 50% ala weapon speed modifier. But then again, none of the other % modifiers do not have lower-end cap, so it's probably not there, but it is something you should be watching out for if you are planning to test it.
Oh, and it appears that imp thread reduction is there, just listed strangely on thottbot:
