Zone file. Look right?

[M & J]

Here is a zone file from my DNS.  The name server is called ns.lightsign.com
The IP of icheeranddance.net is 209.91.106.8
Does it look as if this is correct?
Should the entry in the first SOA line be ns.icheeranddance.net or
ns.lightsign.com because that is the name of the DNS name server?
Any suggestions on what could imporve this file?
I am using bind 8.2

Thanks
