Floor mats are a must to protect the carpet. They don't weigh that much and are much easier to clean when they get dirty and replace when they wear out. My Insight has mats on both sides and still gets 60 MPG. Only exception would be if they come with rubber floors like old 9C1 cop cars. 
No need for a car cover for me as it will never sit long enough to need one. But I expect custom fit models in every fabric will be available from the aftermarket, even with licensed logos.
