I've never used SSL stuff before and just want to make sure I have it right before I go through with it. I have made a huge IM chat program and am trying to make it better (and learn new things). Do I have to change any of my other code? Here is my whole server code (modified to cut down on code lines and hide certain things I don't want people to know...
Would I have to change my client code too (change it to using SSL)?

That code looks alright to me. And yes, you need to start using SSLSocket in the client as well, using SSLSocketFactory. Fortunately, nothing needs to change in both the client and the server except the lines that create the ServerSocket (server) and Socket (client). You can even keep the reference types as ServerSocket and Socket, as SSLServerSocket and SSLSocket provide no extra methods you need. That way you don't even need the cast to SSLServerSocket you have.
