There are many ways to get from Venice's Marco Polo Airport to the city of Venice.
Public Transortation
ATVO Fly Bus - The Fly bus will take you to Venice (Piazzale Roma). The price at the time of writing was 3 Euros (timetable)--A bus is also available to Mestre.
City Bus number 5 takes you to Venice, number 15 to Mestre. An inexpensive option, but you probably don't want to use it when you have a lot of luggage. Like most local busses in Italy, buy a ticket at a tabacchi (tobacco store) or newsstand. There is one at the airport.
Alilaguna offers many connections via boat between Venice and the Airport for 6 to 15 Euros. You'll need to take the free shuttle to the landing. (map of routes) (timetable) (prices)
