Since it's virtually new, all I would do is change the oil before storage and add a fuel stabilizer. Some people fill the tank, others leave it a 1/3 or 3/4. On vintage cars, you typically want to top it off due to moisture in the gas tank.
Some people also "over-inflate" their tires to say 60 lbs. In all the years of storing cars over the winter, I've always kept them at 35 lbs psi and never had a flat spot.
In regards to a car cover, when indoors I keep mine uncovered with a window cracked open. I don't mind the minimal dust and it cleans up easily enough in the spring.
Car covers can range for $50-$300+. I'm not current on the latest, so try doing a search or hopefully someone else will chime in with product information.
