A zone needs 2 or more name-servers. To the outside they will look the
same, internally one will be slave. For full control you might want to
run the master nameserver yourself. A slave should be be at a different
location. Either get somebody to reciprocate (you serve his domain, he
serves yours), or get some cheap/free outside service. I'd opt to not
serve as public dns server myself. Rather go to a place like
zoneedit.com. It is easy and virtually free. To assess your options,
install bind and get familiar with it. Run it to serve names locally.
Get a book on DNS&bind.

If somebody wants your ip-adress they are going to send you an email or
request a web-page or whatever. A DNS lookup is insignificant in comparison.

At least it is a learning experience. If you only have one public
ip-adress there is not really any point, since that one public ip has to
remain static. If it ever were to change, the glue-record in your
parent-zone would have to change so you would need to involve outside
people, i.e. the independence would be illusory. If you have more than
one public ip-adress, you would be able to implement changes to that
second address without involving outside parties (execpt for the
automatic zone-transfer to your secondary DNS-server).
