jQuery chat queue

The spec for this has changed a lot and due to time constraints the code developed in a piece meal fashion. The problem that I am trying to solve is to develop a queue of chat requests with a Sharepoint list being used to store them. This is the jQuery part of a page that contains a table which reads from a Sharepoint list and updates the list when the chat has been responded to. It is working but looks a bit spaghetti and I would like to make it more robust and improve performance if possible.
