No to both. The only thing Ki Arrows does is replace the base damage of the bow (or the arrow, technically) with your current unarmed strike base damage. It does not in any way make the attack count as an unarmed strike.
The Ki Focus Bow ability gained at 17th level does that. It's not at all clear what exactly works with it, but even though Stunning Fist-like feats should work, Shaitan Style's wisdom-to-damage doesn't stack with the Zen Archery anilöity doing the same, as per this FAQ.
