No, by reducing the input voltage by half the output voltage will also be reduced and will not have enough voltage to operate the fixture it is connected to.
You don't. A ballast with a 347 volt input is a commercial ballast. The 347 volts comes from a 600 volt three phase four wire Y system. You can change the ballast out to a 120 volt and rewire the unit but in most cases it is cheaper to buy a completely new lighting fixture.
Yes, 220 volts is in the same voltage classification as 230 volts.
Unless the ballast is a multi tap primary you can not rewire it for 220 volts.
No, not a good idea. You have to use a 347 volt ballast.
Is it incandescent or flourescent? If it's incandescent it will work okay--it'll be dim but it will work. A fluorescent probably wouldn't fire. Now having said that, if this is a European lamp google "110v European base bulbs" and you'll find light bulbs that work on 110v but have bases that screw into European sockets. Just change the plug on the lamp and you're golden.

The terminology T8 suggests to me that the fixture is a fluorescent fixture. These types of tube fixtures need a ballast to make the tubes ignite. If you are trying to operate this type of fixture on 220 volts, you will need a ballast that requires a 240 volts input voltage source.

...90 volts...
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.
A volt is a volt is a volt.

Operating at half the required voltage, the lamp will not operate at full capacity if it comes on at all.
