They're both likely Attuned and Empowered lightsabers (Requires 3 levels of Force Adept) which grants a +1 Force bonus to hit with them, and +1 dice damage. This also nets her 1 Force Technique (Force point recovery is the standard first choice) and thus qualifies her for Force Disciple.
To represent her training in Jar'Kai I simply gave her a few Jar'Kai Lightsaber form force powers from the Jedi sourcebook (plus the Dual wielder feat line).
That works. Her lightsabers most likely to me are just a new crystal attunement (per Jedi academy book/kotor).
