Cracked glass

The glass in the door has cracked. Handle broken too. It seems I need part 338 and 365. I have 3 questions. 1) It looks easy enough to replace the glass assuming I purchase the replacement. However, are all of the other pieces of the door reusable, i.e. when I take it apart to remove the broken glass can I reuse the old pieces when reassembling? 2) The handle I have is in 3 parts - 2 are still in the oven door and the piece in the middle broke. Will this handle, 365, replace all 3 pieces? 3) Is it possible to just buy a new door instead of the pieces? Would that be cheaper?

Thanks!
