Your gear is on the right track, do not be so concerned about keeping Crit above some arbitrary threshold. My gear is exactly the same on left (including Levi EX book). Right side, neck can be either HA or Daystar (doesn't really matter, Det vs PIE), other slots "should" be High Allagan but if you have nothing else you want to spend soldiery on, you can buy the Daystar if you want. It was/is sufficient to clear Turn 9.
