You either want a completely empty or a completely full tank. This stops air in the tank reacting with the water in the fuel and rusting your tank.
I'd be tempted to apply a liberal coating of WD40 around the electrics as well to both drive out moisture and to stop things becoming too dry.
If you're only storing for a few months, it's probably not worth bothering with much else engine wise. I cracked open my 748 engine after it has sat in the garage since last May and there was plenty of oil around the insides!
