IMHO the bilge pump SHOULD be wired directly to the battery. I like to have the float switch powered directly to the battery. This way, no matter how I (or anyone else) sets the switches, if the water rises high enough to trip the float, the pump will come on and do it's thing.
I also have a separate power line running through a switch on the panel to the bilge pump. This one I can turn on and off. It's helpful for draining more water than the float switch, and if the float switch fails I can still turn on the pump.
Regarding your question about re-wiring, it sounds like a lot of work to me. If your existing wiring is in poor condition, black, oxidized, or otherwise nasty, then you should bite the bullet and replace it. OTOH, if you just don't understand it, take some time and go through it. Perhaps you are just missing a switch or two.
