My suggestions are:
1. Hammer - to add to the damage he deals with his natural attacks
-Claws of the beast - to add to the number of attacks he can do per round
-(Or possibly expansion (to increase damage dealt and reach)
2. Definitely psionic lion's charge - to allow him the use of both his uber-speed and flurry attacks
-Strength of my enemy - to use on his unarmed strikes as both a buff and debuff
3. Claws of the vampire - to heal himself a bit here and there
-Greater concealing amorpha - because full concealment automatically negates the ability to directly target him, and furthermore grants a 50% miss chance on all attack rolls against him (and this can't be bypassed through any means)
4. Psionic freedom of movement - because his main schtick is mobility, and avoiding anything that could weigh him down is very much a priority.
-Either psionic dimension slide/door or weapon of energy...for obvious reasons. Note that weapon of energy can be used on his unarmed strikes.
5. Adapt body - this will help him to survive in your adventures among the planes.
-Either psionic dimension slide/door or weapon of energy, whichever he didn't take earlier.
Might I also suggest that he take the Hidden Talent feat, rather than Wild Talent? Having an additional power known will be a great boon (expansion!). Also, Linked Power, from CPsi, will help him buff.
If this heads into epic territory, I'd suggest working on levels in either psychic warrior or psion, then head immediately into either anarchic initiate or illithid slayer.
