Flask of Spring Blossoms for agility. Sauteed Carrots give +250 agility, but there's a 300 one and i don't know it yet.
Also, fill in your raid composition here (takes 1 min): http://raidcomp.mmo-champion.com/
You will then see which buffs/debuffs are missing, which you can fill in with a pet
Get the Raid Checklist Addon for seeing what buffs/debuffs are missing. Far easier to see it ingame and have it done automatically than to use raid comp website tools which require manually adding your whole raid.
You will probably need to go with the +250 agi food until you can level up the Way of the Wok or the market gets a bit more saturated, as right now the +300 one is probably insanely expensive (even the +275 agi one probably is).
