They left out the best place: cemetery.
What I recommend is this:
Start the quest on the jailer segment.
Portal to cemetery.
Grab the unique outside if he is there.
Grab two NV stacks inside the crypts. bonus points for any of the events.
There is usually a shrine in the cemetery, if it is fortune, save it.
Go back to halls of pain level 2, work your way to the jailer, you should have five stacks if you clear his level.
Portal to town, use the pad to cemetery, grab the fortune shrine, pad back to town, use your still-open portal to get back to the jailer and kill him before the fortune shrine runs out. There could also be a fortune shrine on that level as well.
Push through to the butcher and finish.
The thing about grabbing two stacks in the cemetery nice and quick is that they should make the loot better on the packs you have to fight on the way to jailer/butcher and usually will insure that you have 5 by the time you hit the jailer.
Starting at the jailer bit of the quest saves you one level and a lot of time in my experience.
Found a windforce while goblin farming tonight, the base dps was only mid-600 though, very disappointing for one of my favorite diablo weapons.
