First off, go for stamina gear over wisdom. Both are useful, but stamina keeps you alive AND (through cann) adds to your mana pool, but wisdom only adds mana.

Second, I'd recommend that you worry about leveling, not loot. Even if you add 40 stamina (unlikely) it won't make you recover HP any faster, which means you won't really level faster. You might avoid one death with that extra stamina, so you might level slightly faster, but you'll have to spend a lot more time worrying about gear, earning plat, and shopping than you'll save.

We shaman are awesomely powerful and can kill stuff just fine wearing only ringmail (or whatever mobs of your level are dropping). The only gear that really matters when leveling up IMHO is stuff like the JBB or your epic.

P.S. But that's just my take on what's best for leveling fastest. If you enjoy working on gear then don't let me stop you.
