Borderlands – How does “proficiency” work in Borderlands

borderlands

While playing Borderlands sometimes I receive the message:

Your proficiency with weapon has
increased to level X.

I have some questions about proficiency:

  1. How many kills do you need to increase a proficiency level by 1? Or does it use another mechanism (e.g. assists, total shots)?
  2. Can I see which is the level of proficiency for each weapon class?
  3. Can I see where I am and what I need to reach the next level?
  4. More important: which bonuses grants proficiency? Are the same for each weapon or are specific to weapon class?
