I don't think Chakra Adept is optional; making two saves for seven turns in a row (eventually) leaves you with less than a 50% chance of getting through without rolling a natural 1. If you fail on a 2? Virtually impossible.
I think the way to go is with either Ki Mystic or Drunken Master, because both get you ki points at level 3, allowing you to start taking the Chakra feats then, plus giving you extra ki to use. If not those, then take vows for extra ki.
That being said, I don't see much benefit to any of the chakras other than sacral for brief utility flight.
