First goal should be NIN AF3, legs and head will be the biggest initial improvements from your current gear. Keep working to the +2 version for all 5 pieces. A bridge piece for feet would be Ballerines from Durinn (Abyssea-Vunkerl). Dust off your AF1 body as well since abyssea buffs remove the need for accuracy on most things at level 90. Your hands are good for now, Ocelot Gloves from Eccentric Eve (Abyssea-Kon) would be a side grade. Work at getting a Loki's Kaften as well in Konchat from Tural for TP/WS. Qirmiz Tathlum would be a good piece to grab for your ammo slot. to improve your haste belt look for a Bullwhip Belt off of Ovni (Abyssea-La Thiene) or a Twilight Belt from Shinryu once you have all your zone boss clears and cacture kills. Atheling Mantle from Orthrus (Abyssea-Altepa) would be an upgrade for your back slot.
For katanas shoot for a Kamome from Sobek (Abyssea-Mis) and a Hochomasamune from Ruminator (Tier 3 VNM in Abyssea-La Thiene) Also cruise the random question and whats better threads. Ninja ideal gearset comes up often that you should be able to get an idea where else you want to head to.
