I'm so sorry to hear about your Mom. I'm a recent orphan too.
Phals have aerial roots (the roots you have outside of the pot) and they are completely normal. Some have more than others. If they are green and firm your Mom's orchid is healthy and happy. Phals love to be repotted, so it couldn't hurt. However, you shouldn't expect to get all of the aerials into the pot. Make sure you get them wet as well when you water your plant.
