have to agree with these two. I also like skin of the hero for the sheer bonuses.
Power-linked shard and Power Repository shards from Magic of eberron make kalashtar the only psionic race worth considering.
Celestial armor is another favorite for my rogue. great bonus to AC, minimal check penalty, high max DEX bonus and gives fly 1/day. I get this first chance I can to make my rogue unhittable.
