The message numbers are an indication of how good your network connection is. The higher the better. Note that these values don't have a chance to get as high with an ultrapeer connection compared to a 0.4 connection. That doesn't mean your connection is worse but rather fewer messages need to be sent with ultrapeer. The Status column is the direction that the connection was initiated (incoming = connection to you) but after that point data flows in both directions. Bandwidth measures by direction the amount of messaging traffic transferred including search results and queries. I don't know enough about the ideal mix of messaging traffic to answer your specific questions.
