Attack speed, need advice

[Choopak]

Hey guys

I would love to know how exactly attack speed from the Tempest PrC work?
1) Does it stack with haste spell?
2) does it stack with haste boost (from fighter or rogue)
3) how about monk air stance?
4) finely, what does NOT stack with it?

Thanks

There is no longer an attack speed bonus for tempest.
