It depends. A 60 watt CFL draws approximately 13 watts. So you could actually put a 125 watt CFL in as it only draws 30 watts.
However most CFLs cannot be dimmed nor are CFLs recommended in harsh environments such as refrigerators or ovens. Also because the coils of a CFL get larger in diameter adn height as the brightness increases, some fixtures may be unable to accomodate a 60 watt CFL let alone a 125.
The new 23 watt florescent bulbs can go in 60 watt bulb applications without any problems. Where the fixture says, "Use 60 watt bulbs," the recommendation refers to a maximum. The 60 watt bulb puts out the maximum amount of heat and draws the maximum amount of current the appliance should experience. No damage would occur if the appliance received a bulb of less wattage.
Yes, the rating of fixture wattages is the maximum allowable wattage that the fixture was designed to operate at.
No, the ballast's output is not matched to operate a fluorescent bulb.
yes, it can be used - single phase voltage of 230v. 50HZ is important
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
You would need a 12 Watt flourescent bulb

An Energy Star qualified compact fluorescent light bulb can save you around $30 over it's lifetime, paying for its self in about 6 months.
As of 4-12-14 there is a 23 Watt screw in bulb supposedly equal to 100 Watt. It is likely there are higher watt bulbs in the flourescent screw in type available today.

If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.
You talk about tubes specifically so I assume the 60 watt fixture is also designed for tubes. In such a case you should not use a higher wattage tube. If you were to replace a 60 watt incandescent bulb with a compact florescent of 75 watts you are correct that the heat would be less. If heat were the only de-rating factor you would probably be okay. Not sure how this is handled in the code.
Not in the least, and you will still save money. A 100W equivalent will use only 20 to 25 watts, well below the 60W rating of your fixture. Much of the 60W used by the incandecent bulb is dissipated in heat. This is where the danger in over-watting fixtures lies.
Apart from no, your question has no simple answer. Fluorescent lamps need a few kV to start them and have a 90V drop when running. All of that is provided by the "gear" needed to run a fluorescent lamp. In a compact fluorescent (CFL), the gear is inside the cap.
