CalebD missed a couple steps.
Secure the top ends of all your running rigging somewhere low on the mast, get the bottom ends out of all the blocks, clutches, etc. coil it up, tie it and secure it to the mast. Have some line or bungees handy to secure all your standing rigging to the mast, after it's released, so it's not all draping and dragging all over the place as the mast is lifted, moved and stored.
And yes: The boom is usually pretty easy-off.
