Which wires specifically? In general, I was planning on going for heat-shrink solder terminal connectors and crimp connectors.
One of the reasons I posted this is because there are quite a few connectors and I am still not entirely 100% sure what I need. Obviously when screwing something in to a screw terminal block, the ring crimp connectors. But when joining wires, I would prefer to use the heat-shrink-solder type, but there are also butts and blades (heh).
I bought this set of terminals, figured I'd need them anyways: Assorted crimp terminals
I am probably going to buy this set of solder terminals: Fancy solder terminals
I am pretty good at soldering (though usually circuit boards, not automotive wires, hence not entirely knowing what to do.) I have easy access to a heat gun as well.

Well, both - the breaker goes on the battery, and it sets the maximum amperage for the entire new fuse block and everything attached to it. The fuses go for each individual circuit. I want to use just one fuse for each circuit, instead of having several different circuits sitting on the same fuse, largely for my own desire for neatness and debug-ability. I could have one main fuse instead of the main breaker, but I figure that they will serve the same function and I may as well go for the re-usable option.
I was going to go for this breaker: Fat breaker
That said, I bought this fuse kit, which includes up to a 35A fuse, which will be more than enough. I also bought this fuse holder, in case I decide to use one main fuse instead of one main breaker. (I figured I'd need both of these anyways for some project, may as well get them even if I don't use them right now.)

In general, I think my system will basically look like this:
Battery 12V + Breaker = safe 12V
Save 12V + ignition 12V (do I need a fuse here?) + Relay = ignition-switched 12V
Ignition-hot 12V + Fuse Block + ATC/ATO Fuses = eight fused circuits
Fused circuits, obviously, feeding from above. I will probably add a 20A switch in line with high-power circuits, just in case, as an emergency switch.
Fused circuits will terminate at something like this Ground Bar.
 
What do you think of this proposed setup?
I do realize that it's kind of overkill for what I want.
But you can probably agree that overkill is better than your car burning down!
