Nope.  You should get a ~/56.  Even so, a /64 gives you ~18BillionBillion
addresses.

Nope, organizations will go for PI ~/48s, and Verizon will be forced to stop
filtering them.
Oh, and IIRC - as it stands now, IPv7-9 are already shot (similar to IPv1-3)
... so IPv10 would be next up, in a century ... or four.

Are you retiring in the next 0-3 years?  :)

As for the lessons learned - it is about scale.  
32 bits isn't enough, double it 96 more times (or 32 more times for just the
network side, if you prefer) and it is enough.
