I can Tl;dr the gear changes you need to make, and give the differences of opinions on pieces that have some controversy.
You're basically BiS except for a few pieces.
I personally don't think hit chest should be used. I'm a huge fan of using Charmed Ancient Bone Bow for the 8/8/8 (agi/crit/hit) and then finishing the hit cap with Dread Pirate Ring or Ring of Precision. Naga Heartpiercer on a Horde Hunter forces compromises to be made in other aspects of gearing.
I think the chest/shoulder looms for hunters are ridiculously overpowered, and should always be used over the hit pieces.
Hogger's Trousers are good, but Smelting Pants offer so much more.
Naga Heartpiercer only boasts 8 more agility at the cost of 8 critical strike. The hit rating on the bow causes you to be able to maximize critical strike gear options while only losing out on a minimal amount of agility.
Build comparison (in battlegrounds):
Bone Bow/Smelting: 1883 health - 320 attack power - 19.99% critical strike - 4.47% hit
Heartpiercer/Hoggers: 1843 health - 338 attack power - 17.95% critical strike - 5.68% hit
The choice is yours
Also note: Foreman's Gloves are BiS for all hunters. The expertise is necessary.
And you need Feet of the Lynx. They scale up to 10 agility in battlegrounds now.
