I really wouldn't worry about the speed ratings. How often are you going to be driving over 100mph? H speed rating is over 130 mph and I doubt there's very many foci that can come close to that. Common sense has to enter into the equation as well. Snow tires are simply not designed for high speeds and one needs to adjust for that.
Load ratings can be important if you are constantly at the full gross carrying capacity of the car (hauling 3 or 4 passengers all the time, load the rear with bricks, tools, etc.).
