Public transportation (bus, metro and ferrocarrils) is good, not expensive and safe. Don't hesitate to use it. For more information you can check the official website (http://www.tmb.cat/en/home) where you can find out how to arrive to your destination, schedules and which mode of transportation to use. I suggest you download the apps too, which are really useful.
Buy a ten ride card, called T10, and you can see most of Barcelona in Zone 1. With your T10 card you can change from bus to metro, so long as your ride is under 1.5 hours. It's worth it!
For transportation from the airport I always book a Mercedes from Taxi Class.
