It will probably not be realistic to get a new pump shipped to me along the way, as we won't be stopped anywhere for long enough.
Yes, bleeding is critical and will be performed at the cylinder, usually in a sequence specified by the equipment
manufacturer. It you don't have paperwork, I can send you our recommendations, which will probably work on any system.
I should also have mentioned that when you rebuild
your system, you will need an electrically operating bypass valve that rests at open, so that your hand-steering system isn't locked by the hydraulics when you turn the autopilot
off. Some pumps have bypasses built in, some don't.
Onward and upward to sailing heaven!
