You looking for BiS for every class or?
I'm not even sure if I know any 100% BiS, but I'll have a go at rogue.
-Lucky Fishing Hat
-Sentinel's Medallion
-Serpent Shoulders / Talbar mantle
-Sentry Cloak
-Defias Armor / Tunic of Westfall
-Forest Leather Bracers
-Scouting Gloves of the Monkey
-Deviate Scale Belt
-Leggings of the Fang / some agi pants that I forgot the name of (green I believe, maybe you can look it up somewhere, they had quite high agi as the only stat)
-Feet of the Lynx / STV fishing boots
-Meadow Ring of Eluding
-Meadow Ring of the monkey
-Arena Grand Master x2 (gave dodge instead of stam back then)
-Shadowfang x2 / SF (mh) + Assassin's blade (oh) / Cruel Barb (mh) + any of the previous alterations.
-Venom Strike / Lil' Timmy's Peashooter.
Thing is, there were numerous ways of putting together gear, but this is what I could remember without having to look up anything.
For other classes I remember stuff like
Glacial Stone (I believe it was) as the main 2-hander for strength users,
Arctic buckler as caster shield,
Twisted Chanter's Staff as caster/hunter staff,
Inferno Robes as caster robes.
