If N'Dru ability was activated (range 2 or further from his allies) and he had guidance chimps would the chimps turn a blank into a crit or a hit?

His new primary value would be three thus I believe he would be firing crits am I right on this?

While attacking, if there are no other friendly ships at Range 1-2, roll 1 additional attack die.

It does not increase primary weapon value, just adds 1 attack die, so it turns the blank into a hit only.

I would imagine the chimps would just throw feces and eat bananas.
