From what I've read, there's supposed to be two nuts to unscrew. There's very thin ones, but they won't budge! What do I do?

There will be 2 nuts, a small one at the shut off and one at the base of the faucet or possibly a drop down line. Both loosen turning left.

Are those flexible braided water supplies or rigid ones ? Either way, they should be relatively easy to unscrew. Use basin wrench for the connection at the base of the faucet and channel locks for the nut at the angle stop

Hope that helps
