Don't go overboard: figure 8, slipped overhand (good for both a slipknot and a quick release,) square knot, bowline, clove hitch, cat's paw, taught line hitch, fisherman's knot, sheet bend, and trucker's hitch will pretty much let you do anything. Do put a diagram of all of them down, you want reminders.
Give yourself checklists of things to do in the order to do them. You'd be surprised what can slip your mind when multiple shits are hitting multiple fans.
Morse code is good. A reminder that ...---... and 3 knocks, pause, 3 knocks are near-universal "I need help" signals are even better. Again, you'd be surprised what you can forget in the heat of the moment.
The biggest, most important thing on the sheet is stuff that's going to keep you from panicking. Fear really is the mind killer.
