How can one decipher the IANA port registration form?

I have created a simple Twisted based TCP server and Android client. I have used my own protocol for this purpose. While I have tried to lay out my protocol in a way which seems logical, this is the first protocol that I have written, so I doubt it conforms to any standards for a TCP protocol, if such norms even exist. However, I did design it so that I could easily add features without breaking backwards compatibility with older versions of the protocol.

To avoid a potential port conflict, I would like to register a port with IANA. I found the registration form here. However, the questions seem to be highly technical, and I only have a basic knowledge of protocols. So, my question is this: Can anyone describe what these questions are asking? And, how one would answer them in general? If possible, please also include how the general answers would relate to my protocol. That way, anyone else who has a similar question can see both types of answers.

Thanks, Sean W.

I don't wish to be unkind but unless you can answer those simple questions you really aren't ready to register a port number request with IANA. Are you sure you need to? Couldn't you get away with configuration of the server and client? or a naming service?
