Do you put all the reactants of each reaction together and all the products of each reaction together?

Yes, and the electrons in both equations would cancel out with each other so you'll just be left with the products and reactants.

Yes, but you may need to multiply the half reactions by constants in order to get electrons or repeating reactants and products equal in order to cancel out completely.

So would this be similar to how in Hess's law we would add intermediate equations to make the final reaction?

^You could say that. I think combining half reactions is less about cancelling out reactants/products and more about fitting them on both sides of the reaction, but it's the same concept
