Everything stacks so that a duellist can raise their AC to insane levels at the cost of accuracy.
I wouldn't say it "specifically states that they stack", but it also doesn't specifically say they don't stack, and they are dodge bonuses from different sources.
IIRC it was said in 3.0 FAQs that they stack, both bonus and penalties, so you can use both fighting defensively and combat expertise at the same time.
There's nothing else that makes me think you couldn't use all these abilities at the same time. Obviously, there is no problem with getting the increased bonus to fighting defensively from Tumble and the one from Elaborate Parry at the same time (also, one is from weaving and the other from parrying...) but I can understand that the expertise bonus can sound weird to someone... In any case, dodge bonuses from different sources stack.
