You can purchase one, or as a first step you can use duckdns.org which is entirely free! Then when you think you want your own domain name you could just switch :-)

For the limit : basically you need to ask yourself how many connection someone if able to do in a second to your server. As an example, my limit is always 15. A bit high but I'm sure I'm not blocking a legitimate one (either from myself or someone else)
For the ssh port : it's true, but trust me you'll be happy to change for something random like 5927 because you'll have far less bit trying to connect or probe your ip, thus your logs won't be cluttered!
Yes you can use your ip, a domain name is just way easier to remember! :-)
