I'm almost afraid to ask about the phrase "add-default-route=yes" in the
dhcp-client configuration. That seems wrong on the face of it since you
should be getting your routing information from RA and not DHCP.

No, no, no, a thousand times no.  I'm sure RA is great for small SOHO
networks and for ISPs as a means to hand out resources, but in a
corporate environment, we hate you.  How many times do the IPv6 people
have to hear that until DHCPv6 reaches feature parity with DCHPv4, IPv6
is dead to enterprise networks?
 
Strange, I have an enterprise network with some segments running ipv6 for 
over a decade ;-)
 
"Parity" isn't enough information; what features are missing?  RA is part
of IPv6, but you don't have to use SLAAC.
I'd say it's the DHC people who need to hear it, not the IPv6 people, but
YMMV.

I have a question.  Why does DHCP hand out router, net mask, broadcast address, etc. in IPv4; why don't we all just 
use RIP and be done with it?

I think you mean IRDP/rfc1256.  We used to run quite a bit of that, too.
