Thanks for asking the questions, I am newer to collecting the cards as well. What I would also like to know is:
What resources are out there checklisting cards etc? (Publications Books or Websites)
One thing I took from the main Board is collect what you like... that has pushed me towards the 1924 Will's set (my most recent pick-up) -
