1) No, not from the international airport, but if don't have much luggage you can walk to the Northern Highway (almost a mile) and catch a bus there into Belize City. About a buck. If you take a taxi it is US$15 (for the taxi, not per person).

2) By bus (Z-Line or Ritchie) via the coastal road it is about two hours; via Belmopan and the Hummingbird it is about three hours. Either way the cost is around US$5.

3) A car gives you the freedom to go when and where you want to. With a car you can do tours on your own that otherwise would cost a good deal. A car makes the most sense if you have several people. Buses are cheap and a good way to meet Belizeans. Most however are recycled American school buses or other buses and aren't particularly comfortable. Taxis most everywhere, except within Belize City, are expensive.
