Everyone I’ve seen try to adopt one of those balls has given it up relatively soon. I’m not sure it’s worth it, unless you can try one free to see if it works for you over an extended period of time.
As for desk, I’ve read a lot on desks a year or so ago, when trying to make a case to my boss for a better chair/desk. While unsuccessful in changing anything myself, the research I did ended up pointing to adjustable standing/sitting desks as being best if you can finagle one. Standing is generally better for you, but you will be better off if you can change your posture by taking a sitting break now and again. Also useful for eating lunch at your desk, for instance.
