Ok, I see, now I know why things doesn't work as they was supposed to :)

Ok, then all I have to do is make changes at Internic and set my machine as primary,
and granitecanyon.com as secondary?  (and of course do some changes at
granitecanyon.com)

Can I use this zone-file (on my new-to-be-primary DNS) as it is then:

@       IN      SOA     domain.com. root.domain.com. (
                        199912122       ; serial, todays date + todays serial #
                        8H              ; refresh, seconds
                        2H              ; retry, seconds
                        1W              ; expire, seconds
                        1D )            ; minimum, seconds
                NS      domain.com.
                MX      10 domain.com.  ; Primary Mail Exchanger
                TXT     "domain dot COM"

domain.com.   IN   A  1.1.1.1
localhost       A       127.0.0.1
firefly         A       1.1.1.1

www             CNAME   domain.com.
ftp             CNAME   domain.com.
mail            CNAME   domain.com.

-zone-stop-

Or do I have to add more?

and, how do I tell to the secondary NS how often it should update?
