Demonhunter lore/advice/options?

I have 4 pieces of Marauders (shoulders, boots, gloves and CHEST) and I have Garwulf's so far, no Tasker and Theo's., and no RoRG of worth yet,mine would cost me 135k damage or thereabouts and I'm not going there. I might be able to roll crit chance/damage on it, haven't really looked yet.

I was saying the other night I like my three dogs BUT I'm guessing it's more beneficial to run the 4 piece set with all pets, even though there's only one dog damage wise WITH the added benefits of all pets?

To make it worse I'll need to replace the chest and eventually the gloves so I have two more piece of marauders to track down I guess. I know there's pants, what's the last piece?

Other than that I WANT another Kridershot, you know, a level 70 one.... 

EDIT: Also have 2 or 3 pieces of Shadows and while it looks cool,it just doesn't look useful. Maybe in HC?

EDIT two: Okay so I can go with head pants boots Marauders, aughilds shoulders and bracers, Tasker and Theo gloves, and Garwulf chest with RoRG,  Or max the marauders with 5 pieces and drop something, most likely the shoulders as the gloves are pretty impressive? And then that leaves aughild bracers on their own, what's BiS at that point?

I'm guessing if my Scoundrel uses a Windforce, my Strongarms wouldn't boost damage only if I use the bow?
