Powers to get:
-Far hand*
-Inertial Armor
-Inertial Barrier
-Telekinetic force*
-Telekinetic thrust*
-Telekinetic manuver*

You have to get all of the starred powers with Expanded knowledge, but that is generally okay as psychic warrior gets a nice amount of bonus feats.
(You do know all of those are in the SRD right?)

Anyhow, that should get your friend's character good n' telekinetically potent.
Don't forget to tell your friend to take defensive powers as well.
