Whats the best way to cut fresnels?
They need to be identical (centers match up perfectly) when done correct?
Should they both be cut at the same time or individually?

That thread helps a little bit. Cut them individually and evenly!. If you need to shorten the height of the lens by say an inch, then take .5inch from the top and .5inch from the bottom. Same goes for the side. Just divide the total you want removed, divide by 2 and cut that much off each side. I really recommend viewing that thread.
