Exactly. This is why you want to have a secondary that works if at all
possible. You also want to make sure your InterNIC contact information
uses an email address NOT in your own domain. Why? Because if your ISP
changes your IP address, you will need to change the host and domain
registration information at InterNIC. If your domain isn't working,
you'll have a difficult time doing it. Alternatively, don't use "mail
from" authorization at InterNIC, use one of the other auth methods (like
crypt) that work from any email address.

Nope. Use a real nameserver, even if it's not a "real" secondary for your
domain. That way queries sent to that secondary *will* resolve addresses
for hostnames in your domain, just not 100% the right way -- it will have
to query your primary first. Someone might log a minor noitce for a
non-authoritative secondary, but it will work at least.

Absolutely. My ISP uses DHCP too, but apparently not dynamic IP
addresses. One does not necessarily require the other.

They used to, and if your nameservers were down they would eventually drop
your domain. That was when domain registration was free. Now that we pay
for domain registration, they do not check for active nameservers, and I
doubt they could legally drop the domain for lack of DNS.
