Is that a good way to fuse something? Why do you need to attach the negative wire to the negative terminal of the battery? Isn't one of the prongs on a fuse negative, the other positive?

I don't see why you would need to connect the lights directly to the battery, unless they are using a large amount of power. Connecting the (-) side to anywhere on the frame of the car should give you a decent enough ground. As for the (+) side I would try to locate the headlight fuse or something similar to connect to, instead of a random fuse like the article suggests.

no it's not. you either want to use an add-a-fuse kit or better, put an inline fuse right off the battery before the relay. you don't have to connect the negative to the battery as long as you can provide a good chassis ground. and no, there's no positive and negative to a fuse. a fuse has power in and power out. so i guess you could say they're both positive.

the article is for aftermarket lights like fog lights. so yes, you want to power it off the battery and no, you don't want to use the headlight fuse.
