Endnote Web - Questions

I am doing my MBA and am new to using Endnote.   I have the Web version through my university, Here are my questions:

  1. Harvard Referencing is what id required in most papers. Is there a way to set-up Endnote to have this as the default so that fields that are not required do not show up?

  2. Is it poissible to have Endnote search a PDF document in my files and compile the refernece from it? Is this achievable by importing the pdf? 

  3. Are the only ways to acquire references by 1) using a university database that is listed or 2) capturing information with capture tool from a website?
