6 Days in Sicily

We will be traveling to Sicily next April arriving in Catania for the first two or three nights.. We are looking for ideas for day trips in this area and then we're on to Taomina for 3 nights and looking for ideas of things to do and see in that area. Does it make sense to rent a car to go from Catania to Taomina? We have been told that driving to some areas are not for the faint of heart so we would also consider hiring a driver and a guide - especially when going to wineries. Any suggestions would be greatly appreciated.
