I generally agree with your list, but I'd like to suggest that a balance of competence and confidence is best. In my experience, one need a certain amount of confidence in order to learn effectively and quickly, and in the working world if you can't do that, all the competence in the world won't help. As to the boss, I think whether or not they understand the difference is not as important as how they assess the results.

Also on the topic of competence, this thread reminds me of an old Shoe comic (anyone remember that one about crusty old birds that ran a newpaper in a tree?). On bird types in his editorial something like "There is nothing I am more proud of than my competance", then another bird reaches in to the text bubble, scratches out the "a" and writes an "e".

I don't mean to be pedantic, I just am ;-).
