Fast/fast is the way to go to maximize poison damage, and you use Wound/Wound.

The ideal build stays the same. In practice maximizing poisons is a minor point. The majority of your damage is going to be white swings and Eviscerate, in fact I think it was something like 86% combined in my best parse. You can definitely work with Anarchy + another drop, since weapon damage isn't going to have any effect on your Eviscerates, and DPS determines your white damage (independent of speed).

If you can make sure you are always placed in a group with hunters (next choice is probably death knights and warlocks, especially destro, basically classes with pets), you should spec close to what Denic has and use two fast daggers. If you find that your group is weak at generating combo points and you have to burn energy using hemo, backstab or shiv more than you like, then you should probably spec Talent Calculator - World of Warcraft and pick up calamity's grasp and webbed death. Some people like me, also put a point in shadowstep for utility, for instance Malygos vortex or moving around Sarth fight, although you have to sacrifice a point in aggression for it.
