Her cat form does not leave her powerless. It just limits her. Remember she told Ichigo once she turned back into her true form it was easy to carry him.

Has far has i can tell and what the admins (well the ones that wrote her page) here think is that the cat form she keeps her power and speed but can't fight (other then hyper fast normal cat fighting) nor can she lift things due to well no arms.

Her zanpakuto is likely lighting but we don't know for sure. Saying her zanpakuto is a lighting type based on her skunpo looking like lighting (it was never stated that it was only Sun Feng years later stated her's was wind). Sun Feng has a wind type Shunkō but her zanpakuto is well we don't know what to say about it. It kills in 2 hits but other then that how? The slabing makes you think its a type of poison (be it poison or her reiatsu posion) but it has never been said to be posion.
