First and foremost you shouldn't be gemming ArP until you're virtually bis/pre-bis in every slot. Agi and Agi/Crit gems are your priority for now.
As for the gear, Mark of Supremacy is garbage. Get Mirror of Truth until you get a raid trinket (DBW, STS, WFS, etc). Needle Encrusted Scorpion is garbage for Hunter, so don't bother. The polearm from Anub25 is a good stat stick until you can get Hersir's Greatspear HC or Oathbinder. Rowan's will be replaced with at minimum ToC25 Death's Head Crossbow; anything from ICC is better. Boots you can either get crafted or the RS25 ones -- they're virtually the same item. Legs will be Northern Lights from Lady 25, pretty easy. As for belt, you're looking for quite literally anything mail from ICC; most of ICC10 gear has hit on it and it goes to waste, but intellect is an important stat for Hunters as our mana is our battery (if you need to stop DPSing to recharge it, big loss). BIS belt is from Fester25, Nerub Stalker Cord. As far as Gloves, Helm, Shoulders, and Chest, you want T10 in these slots. Cloak is fine for the time being, you'll want the EoF one (Recovered Scarlet Onslaught Cape) after your tier pieces however; this is BIS until ToGC25 cloak. Neck is fine for now, only upgrade are necks off Sindra 10 or 25.
