if a 20w light bulb was to smash while still screwed in and i was to touch the coil inside the glass while the mains and switch were still on. Would there be 240v flowing through the coil?

There would be no coil, as it would burn out instantly in free air when you switched on!!! You would have the two supports with 240 volts between them, if you touched both you would get a shock.

There would be 240V across the coil even if it broke, which it probably would. Voltage is always measured between two points; it does not flow.

Yes. You'll need rubber gloves (insulated) to get it out. It's a real pain when that happens. If there's a switch, make sure it's off, and even then there might still be some current so be very careful.

The nature of the circuit would change when you touched it. The filament is a resistor, but when you touch it, you become a part of the circuit unless you're so well insulated that you look like a resistor of infinitely many ohms to the voltage source.

Voltage is the "pressure" that forces current through the circuit, so it's actually current that flows through the filament.

yes. the wattage of the bulb is to do with the resistance of the coil inside, not the current from the mains.

Er..... yeah, take the safe route and turn your supply off at your fuse box/distribution unit, better safe than dead!
