You will see my posts from last year. Your motor should be very similar to mine. As for shower and heater, I'm not sure as i do not have those luxuries! My guess would be to blow out lines with compressed air.

I drain out my heater just by blowing into one end of the hose with the other disconnected and sitting in the bilge, then I hold up one hose as high as I can and pour non-toxic anti-freeze through until it comes out the hose in the bilge. For the shower, I'd do something similar and be sure to run the pump briefly to get the non-tox through there as well.
