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.

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).
