You can check which saber- or force-form an NPC currently has selected with the IsFormActive() scripting function. Set the first parameter to the NPC you wish to check and the second parameter to one of these constants:

FORM_SABER_I_SHII_CHO
FORM_SABER_II_MAKASHI
FORM_SABER_III_SORESU
FORM_SABER_IV_ATARU
FORM_SABER_V_SHIEN
FORM_SABER_VI_NIMAN
FORM_SABER_VII_JUYO
FORM_FORCE_I_FOCUS
FORM_FORCE_II_POTENCY
FORM_FORCE_III_AFFINITY
FORM_FORCE_IV_MASTERY

As for passive feats, they are always active, that's what makes them passive. So you can just use the GetHasFeat() function to check if the NPC knows the feat. The first parameter is the line number in feat.2da for the feat to check for, the second is the NPC to check.
