Just noticed something. Have your serial number reflect the date you last updated the file. That way you will know when you last changed it. For example, today is September 27, 2010, if you were making your first update today, make the serial number 2010092701. I add on 2 digits at the end in case I need to make more than one change in one day. Changing it 10 times in one day isn't likely, but just in case that isn't enough, I know *I* will not be making more than 100 changes in one day. Serial numbers ALWAYS have to increase with each change. That is the way other name servers know they need to update their information. If the serial number is bigger than what they have stored, then they know they need to download the new information. If you plan on updating the DNS information more than 100 times a day, you will need to give yourself some extra digits. I hope this is of some help.
I think that the fine manual mentioned something about if one hundreds edits were done in a single day, then it is time to go home and get some sleep!
