I would advise against multiple connections for the different information. I would design some protocol that contains a header with information to be processed. Use as little resources as possible. Also, you may not want to send updates for various positions and stats from the client to the server. Otherwise you may end up in a situation where a user can modify their data being sent back to the server.
Say a user falsifies a monster's location to get past something. I would only update the user's position vector, and actions. Let the rest of the information be processed and validated by the server.
