Squad leaders' attacks are still off (my error earlier too since I wasn't paying attention to the feats included):

Attack: Lightning Club +5 melee (1d6+3plus 2 electricity )
Full Attack: 2 lightning clubs +1 melee (1d6+3 plus 2 electricity)

The lightning club is not a light weapon, it is an exotic one, so the penalty for wielding 2 is -4. for both hands instead of the normal -6 for primary hand and -10 for off hand. because of the TWP feat. The bonus damage includes the point from weapon focus now too.
