Psychic Warrior into either Diamond Dragon, Elocater, or Warmind. Also, Psychic Warrior into Acetokineticist or Sonokineticist (both are variant Pyrokineticist PrCs found in the Mind's Eye articles).
Psychic Rogue into Elocater. Also, Psychic Rogue into (gasp!) Ebon Saint. IMO, the only way that PrC is even viable.
