I would say the recommendations are a little over the top. From my experience, only the following is needed (at least for Tyr's Hand):
- Level 60 rogue
- Talents Master of Deception and Camouflage
- Glyph of Pick Pocket
- Boots which increase your stealth level (like Nightscape Boots)
- Enchant Cloak - Stealth
Picking the whole area is easy, the mobs only see you when you directly stand in front of them (which you do not have to since you can pick from 10 yards away). Average gain in Tyr's Hand is about 80-90 boxes per hour. The whole farming for "exalted 999/1000" takes about 16-20 hours, if you started at "11999/12000 honored".
