1) I was quoted just over $200 by my dealer, but I'm going to change the seal myself.

2) The reason they need to upgrade the software doesn't have anything to do with the initialization. It's because BMW realized the old seals weren't good enough, and the replacement seals are thicker. Doing a manual initialization (easy to do yourself) might not always work because of the tighter seal triggering the 'entrapment' response which will prevent the sunroof from closing and completing the initialization cycle (this may or may not happen). The software update takes into account the greater force required to close the sunroof against the tighter seal, and guarantees the initialization will work properly. Try changing it yourself, and if you can't initialize the sunroof properly, then you'll need to take it in for the software upgrade.

To the O.P., if you want a pdf of the service bulletin on this, PM me with your email address and I'll send it to you.

Bottom line is that they fixed it under warranty so why sweat the details?
