Assuming a full Wizard, and one that PrCs out @6, only L1 maneuvers are available. Moment of Perfect Mind is probably the best.
If you delayed that one level (such as Wizard4/Martial Adept1/Wiz+1), you could get L2 maneuvers. Shadow Jaunt is wonderful for non-combat teleportation, Shield Block & Zephyr Dance help with AC, and Action Before Thought aids with the occasional Reflex save.
