question about setting up bind

I'm setting up BIND and I've come across some problems. Please don't berate me too much but I'm still trying to learn.

Anyway, at a friend's suggestion, I added A records in my domain's zone file for the name servers. So here's what I have:
Code: 
@   14400   IN  SOA ns1.mydomain.com.    email.address.com.    (
                    2004012511
                    7200
                    7200
                    2419200
                    86400
                    )

mydomain.com.    14400   IN  NS      ns1.mydomain.com.
mydomain.com.    14400   IN  NS      ns2.mydomain.com.

mydomain.com.    14400   IN  A       192.168.0.210

ns1              14400   IN  A       192.168.0.206
ns2              14400   IN  A       192.168.0.207

; Other A, CNAME, and MX records follow
Obviously I changed the domain/ip addresses here. This seems to work ok, but I don't know if the A record for the name servers are even necessary. The registrar for the domain in question is GoDaddy and they require you to enter the IP address for the name servers as well as the domain name when using custom servers.

DNSReport.com doesn't seem to mind as I don't get any errors related to this, but running dlint gives the following:
Code: 
ERROR: ns1.mydomain.com. has an A record of 192.168.0.206, 
but no reverse PTR record for 206.0.168.192.in-addr.arpa. 
can be found on nameserver ns1.mydomain.com.
 The following resource record should be added:
 206.0.168.192.in-addr.arpa. IN PTR ns1.mydomain.com.
And the same is repeated for ns2.

So my questions are: 1. Are A records for the nameservers necessary? 2. Could I add the rdns like dlint suggested even though I don't have the delegated authority for that particular block of IP addresses? Should I even care? 3. Am I missing something really big here? I've kind of jumped head first into running my own DNS server and I haven't read the thick O'Reilly book on BIND yet.
