I would suggest that, after whatever organs are viable for transplant, you should leave your body to science. Find out where your local teaching hospital / medical school is and contact them. They always need more cadavers than they can get. If it became the norm for Pastafarians to leave their bodies to the advancement of medical science, we would get thousands of converts from the medical profession.
If you like, you could get your body delivered to the hospital by a bunch of grogged-up pirates in full regalia. I have had the misfortune to meet more than a couple of medical students in my time, and that sort of behaviour would not turn too many heads with them. If someone tries to stop you, it is an infringement of your religious freedom (if Jehova's Witnesses can legally kill their children by refusing blood transfusions, then who could possibly object to a bunch of pissed-up pirates walking around carrying a dead body?).
