The problem with DNS being down is just as critical on IPv4 as with
IPv6.  The only difference is that it's a lot easier to remember or type
IPv4 addresses ... at least now until we're really getting used to
IPv6 addresses.

By all means, DNS will be much more critically important in IPv6 though
- as not everyone will be able to remember IPv6 addresses as well as
IPv4 addresses.

Nope, ARP is gone.  But it gets a replacement as a part of IPv6, instead
of ARP being an addition to IPv4.
