TiVo just uses the channel listing provided by your cable company so that would be correct if that is your local lineup. They don't offer any option to change the channels numbers locally.
Under settings and channels you can remove any duplicate channels you want. Most people remove the SD channels so you only see the HD channels.
As far as getting to My Shows quicker, I usually hit the TiVo button before I even turn the TV on just to make sure I am not on live TV. Then I hit TiVo again. There might be a TiVo+# shortcut, but unfortunately no on the current remote there isn't a button for the shows.
