Tail dragger tactics by Imeson is very practical.
Ensure your tailwheel endorsement course includes solo time. Quite a few schools don't allow you to solo which then proves awkward when wanting to join a syndicate and you have no solo time.
Insurance normally is looking for 25 hours on tailwheel experience.
Typically a minimum 8 to 10 hours is required for your endorsement, if you are going to cover wheel landings and crosswind technique. Taxying in a crosswind is interesting.
Stay current.
