Steve;
        I do not think one fuse/breaker will do what you require. These
devices should be matched to the load they are protecting. For instance I
would not try to fuse the starter.It draws such a large and varied
current it would be hard to get trouble free service. Even if you did get
a good match a short in a smaller wire would cause a melt down before it
tripped the starter fuse. See what I am getting at? So each branch would
need it's own fused service, or in other words a fuse block, which you
already have.
        I agree with you that electrical protection is a good thing. I am
planning to add a separate feed and relays  to the headlights. I will
branch off the positive terminal with a fuse rated at about 25% more than
all four lamps draw. Then I will fuse each light 10% over.
Drive Safely & Good Luck
