1. AGM
2. Inherited Insignia of the Horde
3. Double Perfect Charged Gears, either 10 Agility, or 7/6 Monkey (The ones you have now are 6/7)
4. Minor Speed to boots
5. Ashen Gloves give more Crit + Agility, worth more than the stam from toughened leather
6. Perfect bracers, either 9 Agility, or 6/5 Monkey (The ones you have now are 5/6)
7. Champion's Deathdealer Breastplate
8. Parachute Cloak with 12 Agi on it
9. Stained Shadowcraft Cap
10. Spider for pet
For the issue of hit cap, I made a wowhead profile of what I believe to be a bis hunter which focus's are
1. Reaching Hit Cap
2. Agi + Crit
3. Stam
4. Etc

(Just imagine the bracers are 9 Agility, also changes to Spec are included)
As for professions, maxed Engineering and Skinning for bis, and keep a pair of the Gnomish Rocket Boots with Cat's Swiftness in your bag to have also.
Overall: 6.0
Hope this helps, gl on getting bis
