Need Clarifications On Moving from Blogger To WordPress

Hi All,
I have got an blog on blogger and planning to move that to word press platform.
Before moving i would like to clarify some points

  1. My blogger url shows like this >> mysitename/2017/12/testpost.html
    but in word press i want to show this as >> mysitename/testpost
    is that possible if so how?
  2. I would like to delete some posts,is it fine to delete? any best way to do this?
  3. While im moving to WordPress then my comments from blogger are also moved or only content?
