I have found that sometimes the Tracking info is more complete and updates quicker on the USPS website then it is if you just click the tracking link on the completed add under MyEbay. As far as shipping preferences I use Priority Mail (print postage at home and drop in bulk box) if I can find a box/envelope for my purpose, everything else goes Fedex 3 day Ground. I print everything up at home and just drop it off at a location down the street no waiting.
