You didn't say which Contour receiver you have so this may not apply to you. But, if you have a Contour 1, you may select favorite channels and then go into settings and change the default guide view to "List Favorite Channels View".
Settings > Guide Options > Default Guide View > List Favorite Channels View
You can also skip channels you don't want to appear in the guide. This will take a few minutes, but you would only need to do it once. You may access a skipped channel later by un-checking the skipped channel or by manually entering the channel number.
Settings > Channels > Set Skipped Channels
