Make an enchanter, farm Strat/Scholo/whateverhighendclassicinstanceyouwant and send the greens to your enchanter. D/e said greens. You get expensive mats, which you can sell, or use for free enchants =]. You can also buy cheap outland/classic greens and d/e them for profit. Heh, its what I do and it works out quite well =]
Edit: To be a little more on topic, with my warrior I usually roll with the darts. I haven't gotten around to getting all my off sets, but Im sure I would use them in an AP set and the Throat Piercers in a crit/avoidance set. The BoA bow, if it has 5ap, would be the best for an AP set overall (not sure about the values =3)
