348 ts Belts and Technical Manual

I just purchased my first Ferrari today. Although the Technical Manual was included with the vehicle, does anyone know of a better owners guide to maintain the car?

From what I am learning there is also controversy about the time between servicing the belts. The vehicle has 49,000 miles, and the last belt maintenance was in 1998 when the vehicle had 30,000 miles. All of the normal service work has been done as required, but can I wait another year and a half until the vehicle would have 60,000 miles, or should I perform the service now since it has been 5 years? One tech advised me that when the car was originally released they recommended 30,000 miles or 10 years.

Thanks to all!
