Lastly, when waas becomes available... is it a simple software upgrade?
and any word on the charge of this upgrade?

My understanding (based on the fact that I am on the list for the 430
upgrade) is that there are both hardware and software changes that will
need to be made to the unit. Therefore, the unit will need to be sent back
to Garmin for an as-yet unspecified amount of time.

One pilot in another newsgroup made the humorous comment that for the
upgrade, Garmin is going to rip off the face place of your current unit and
glue it onto a completely new unit.
