I have all answers in the item description:
--------------
* Tutu only rigged to the waist, pelvic and spine bones. To handle possible hands and legs intersections, use control morphs and/or tweak limbs animation from within your clip.
* If you plan to bake a cloth animation for tutu, do it as the last step. Once vertex animation is baked, morphs would stop working.
* Natalie character comes with breath morph. Once original skirt is replaced with tutu, you will not be able to use that morphs and should delete it and recreate. Guide for creating a breath morph in CC:

For physics, it's very subtle, but you may try adding self collision.
