CB Conditional can show/hide fields/tabs based off other fields, but not based off URL. You can find a CB Conditional tutorial below to get you started.

For URL based usage you'll need to use CBSubs and hide irrelevant fields to your various plans by editing them and selecting plans to hide on the Workflows tab, but this only hides them on registration. To hide on profile with CBSubs you'll need to install CBSubs Fields Tabs Protection and protect various fields/tabs based off the owners subscription. CBSubs usage is detailed within your CBSubs documentation.
