The Ford Barn

I've got a 1936 ford coupe that I've been rebuilding from basically ground up. I am at the point now where I'm trying to sort out the wiring harness. I have an E-Z Wiring 21 harness and am trying to figure out what to do for the light switch as the way the kit is set up for lighting is much different from how the car was from the factory.

The fuse box has separate wiring for the different lights, where the factory light switch on the car seems to have a power in and then junctions the lights all from the switch. So i was planning on running a slightly thicker power wire from the headlight fuse on the fuse box with a larger fuse and then sending that to the light switch. My concern is that the light switch might not be able to handle 12v

Another question I have is the floor starter switch was wired up directly to the alternator and then from the switch to the battery. I have it wired up the same way right now, but before someone had a 35amp alternator running to it, and I have upgraded to a 100amp (I'm hiding a headless sound system behind upholstery). Can that floor switch handle acting as a power block for that amount of amperage or should I route the alternator straight to the battery now and then back to the starter switch?

I'm sorry for any ignorance on these topics as I'm largely self taught, I can update with any pictures requested tomorrow when I go into my shop.
