Yes, one says on which machines it runs, the other says how fast.

No, they are orthogonal.
You should specify both.

Yes, they are for the N different version of those chips.

Yes, that's all it sets, +DA.

>I don't know if there is any difference between say just specifying:
+DA2.0 +DS2.0 and +DAV2000 +DSV2000 and +DAV2500 +DSV2500

No.  Only the deprecated +tm has a difference.
