Is there a gradation of proper and improper deeds?

When somebody asks if it's OK for a Buddhist to do this or that, different answers may be given: - It goes against n'th precept - It is an unwholesome action - It will produce bad kamma - It will cause rebirth in hell - Anything else? If there is something more, please let me know. Other possible answers may include: - It does not break any precepts - It is a wholesome action - It will produce good kamma - It will cause rebirth in heaven - It will lead to nibbana/enlightenment - Anything else? If there is something more, please let me know. I wonder which of these things are completely equivalent (e.g. is an unwholesome action exacly the same as an action that produces bad kamma?), and if there is a gradation of these things (e.g. is breaking a precept worse than an unwholesome action that doesn't break a precept?).
