So long as the batteries are at full charge, they will be fine to leave in the boat. A good practice, though, is to unhook the leads from the boat to minimize battery drainage, but leave your charger hooked up to it. Then, every month or so, plug the charger in to quickly top off the batteries. They will be ready to go in the spring.
Fogging is a good idea as it helps keep the cylinders coated. A good stabilizer through the fuel system is very helpful in keeping the fuel system from potentially gumming up.
At a minimum, check the lower unit fluid. Usually it is good practice to change it once a year (in the fall) to ensure no contaminants are in the fluid, and checking as indicators to any bigger problems, like a bad seal.
From there, you should be good to go.
One big thing, though... After starting the motor for the first time in the spring, be sure to have a second set of plugs ready to go in. There is always the potential of having a plug get fouled due to the amount of fogging oil in the cylinder. I know some of the newer motors have a different set of plugs which can be costly as compared to the typical 2-stroke $3.00 plug, but it never hurts to have a spare ready if you choose not to switch out your plugs.
