You can't reorder the channel numbers or anything like that.
But you can set your channel list and setup your favorites in the same channel list screen. Then you can go to the guide, tell it to display favorites (i use it for all my HD channels). Then you can use the filter feature in the guide to only see sports, movies...etc.
