The MMPI is a good personality index, however, it's strengths lie in Axis I diagnosis, not personality disorders which are Axis II on the DSM multi axial diagnostic tool. Better would be to have the MMPI and the MCMI (Millon Clinical Multiaxial Index?) together. The MCMI is a better instrument for looking at personality disorders (Axis II). Using them together allows the diagnostician to look at the person's personality functioning over acute and chronic Axis I and Axis II issues. I believe and it's been my experience that this gives you the most useful and clearest diagnosis as compared to using only one of the two listed above. The battery that 90pmhinneutral underwent sounds like a very well-rounded, thorough one, though it's not always practical or possible for all clients to experience that.

Good luck.
