For the protocol, look into Jabber/XMPP, instea of reinventing the wheel, so to speak.

For Java networking and UI examples, see the wiki: http://www.developer.nokia.com/Commu...tegory:Java_ME

Importing libraries is an implementation detail. First you may want to consider picking a technology. If you want to learn about these things, Wikipedia or Google can provide a staring points. Like http://en.wikipedia.org/wiki/XMPP is the XMPP article on Wikipedia, and http://xmpp.org/ is the actual site where it is maintained.
Also, in the Wikipedia article you can find related readings on the bottom of the page, links to other articles about instant messaging protocols, and the concept of instant messaging.
Then you pick a protocol, and you will see if you need the JSON library or not.
