Hi John. In addition to what you're planning, and your weather conditions, and depending on how long it's been since the following were done....
1) Bleed the brakes (AND clutch) to put new fluid in the system.
2) Use stands as suggested above so you can leave the handbrake off (and not worry about tire flat spots).
3) If it's humid where you are, depress the clutch and have an assistant place a wooden wedge in position to hold the arm on the clutch cover "extended" so there's no chance the friction plate will rust to the flywheel.
4) I've heard arguments both ways regarding the antifreeze. For six months, I'd put in fresh fluid and leave it "wet".
5) The dehumidifier is a good idea. If it's not practical, leave the car in a locked garage under a dust cover, with the windows slightly open. Leaving them completely closed can result in mildew on the headliner and door cards.
6) The fuel system is another question. You MAY want to siphon out excess fuel. Then clamp the fuel lines closed, start the engine and run it until the float bowls are dry. This will minimize the chance old fuel will gum up the carbs or tank. On the other hand, if humidity is high in your area, leave the tank full for now... but run the float bowls dry as I mentioned.
7) Don't forget to wash and wax the car before storage and include a thorough cleaning of the interior.
8) Fresh oil changer BEFORE you leave for the U.S. Don't leave old oil in there during storage.
9) Leave a note for yourself on the dash reminding you of all the steps you need to "undo" when you are ready to restart the car.
10) When you DO bring the car to the U.S., make sure you have new DOT approved tires installed. We only have about three tire choices over here for 10" rims and you'll pay a premium for them. I suspect you'd pay less for a set of Yoko's over there than here.
