Flyby Attack, especially if you use metamorphosis on it (use it as a mount!).
Also, yes, you can use both Life Sense (LM) AND Mindsight (LoM) on it. Makes you damned hard to sneak up on.
But yes, giving it White Raven Tactics is awesome.
Hidden Talent doesn't count as a manifester level for the purposes of feats and such.
Give it Quicken/Extend/Maximize Spell-Like Ability, if it can qualify for them (I don't remember what the prereqs are). According to the portion of the book regarding psi-like abilities, all powers are considered psi-likes, and they qualify for those feats as if they were spell-likes.
