Cheaper way to go to the city is bus line 12 last stop Capitello (information summer 2012) which is 250 meters from the airport (continue straight from the airport bus stop of number 8 as if the bus was going straight between the rent-a-car garages, and not turning left to pass between the rent-a-car offices and parkings.) which runs to the Gare d'Ajaccio (train station), and costs just 1.10 Eur, however it is not advertised by Tourist Information at all. All the plans and timetables can be found here: 
A ferry can be taken to the city from Nice, Toulon, Marseille or Porto Torres. Companies operating ferry boats are : Corsica Ferries, La Meridionale and SNCM.
Summer seasons are generally busy, and thus it is advisable to book in advance.
Rent-a-cars are better to be taken at the airport, however watch out for the cleaning policy of the cars: AVIS/Budget warn you to return them the car in clean state, otherwise a penalty of 50 EUR might be charged. There is a BP Fuel station between Ajaccio and the Airport, which has both vacuum cleaner and pressurized water cleaning, which will cost you around 2 EUR to clean the car.
