I've owned a 1964 330 2+2 for going on three years, and can comment on your list from my experiences:
1. Expensive, almost always yes, and sometimes difficult to find, but usually not impossible.
2. No, if it was properly maintained in the past and the good maintenenance continues. Ferrari V12's were designed for long-distance, long duration racing and are very stoutly built.
3. Yes, the extra four cylinders are four more cylinders that require man-hours and parts.
4. On my 330, just about all repairs short of a complete block rebuild can be done without taking out the engine. The engine compartment is roomy and easy to get around in. Later front V12 models, such as the 412, are more crowded by the bigger 4-cam engine and a lot more power stuff as well as the injection system.
5. The 330 can be worked on with standard metric tools for routine stuff.
Once again, on a later and more complex car like the 412i that has fuel injection, you are probably looking at more special task-specific tools.
I can't comment on the injection. I leave the carb tuning on my car to the experts.
