Help Please - Rewiring and installing new fuse block

Am in the process of installing a new fuseblock (Blue Sea 5015) en route to rewiring the entire boat.
Problem is... I just don't know where to start. Is there a good source to learn how to re-wire and connect safely and appropriately??
The folks at Blue Sea suggested that I need a primary fuse or circuit protector between the battery and the fuse block. Why and what should be used.
The wiring of the fuse block is straightforward. The connection to the switches is another story. The contour swtiches have three prongs on the back: one for + in; one for + out to radio or whatever; and one for ground. I understand the first two, but not the third...
They said to run the negative as a ground to yet another terminal, separate from the fuseblock and separate from this other main fuse. What????
Sure would appreciate any help. I am an electrical idiot...

The primary fuse is in case of a short
BEFORE the fuse block. It should be close
to the battery.
The negative is for the pilot light in the switch. Run it to a terminal block (since

Thank you Chuck!
BTW Why do you say a DP for the running lights? Flip up for bow light only and flip down for bow and stern light?
If so, do I just run a splice wire off of the bow light to the other circuit / pole?
Very much appreciated,

Yep, flip up for running and down for anchor.
I gotta run and go do a slide show of my
photos for dive club, but I'll post the
circuit here when I get a chance.

I don't have a way to post graphics here,
so I'll try to do it in words. The DPDT
has eight terminals:
A1, A2, A3. One half the DP part can connect
A2 to either A1 or A3.
B1, B2, B3. The other half can connect B2
P. Pilot Light +12 side.
They will be laid out like:
P & G could be anywhere. On mine I think

Can't thank you enough.
