I've usually kept the vehicle weight on the ground and used an impact wrench on the nut and its worked.
As it is rubber mounted at the top of the damper then this can absorb some of the impact from the wrench and cancel out the torque being applied. Also may be worth using a long breaker bar if you can get it in the space
Can always spin it on a couple of turns to jack it up again
Maybe take it to a garage with a bigger impact wrench to see if it shifts
No, it would have to be a complete axle set at the same time for the handling not to be compromised
Powerflex are the best ones to purchase from experience but may cost more
I would put money on it being the turbocharger variable vanes sticking due to excessive carbon deposits
Try using a cleaner to remove the carbon - links below:

Could also be an adjustment required on the gearshift mechanism which has to be in Park to allow the key to turn back far enough to be removed
Try wiggling the gearshift to see if it makes it easier to remove the key
Sorry, misread your post....thought it said 'front locks'
Its possible but not sure....again if a scrapyard has the parts you can take measurements or offer it up....sometimes the manufacture won't change much metalwork to facelift a new version just superficial plastics...so certainly worth a punt and time in research
You could get one made by Samco or other companies offering silicon hoses
Any colour and also length, bends, etc

Also, check out Demon Tweeks as they do hoses

Yes that is correct and the earth pulses the injector
Cannot remember exact voltage but think (distant memory) that it is battery voltage (12 volts upwards)
It could be a vaccum leak in the engine, defective clutch springs or Dual Mass Flywheel worn, engine mounts....so many things it could be so worth dropping into a garage for them to diagnose
Usually water collects in the scuttle panel area below the windscreen and accessed from the engine bay.
If you have a sunroof then sometimes the water can travel down into the area you describe where it should drain out but if the drains are blocked then this may be the reason
Maybe the pads are sticking in the carrier - best to remove pads and see that they are free to slide sideways, if they are seized then they will need cleaning up (sometimes have too much paint on them) and copperslip to ensure they don't stick in the future
You should be able to use one of these to resolve the issue - Towing Can Bus Relay

The vacuum kit looks like it should do the job nicely and at least you'll know there is no air left in the system.
Check also the thermostat is not stuck closed but you should find that out if you can measure the temperatures before and after the stat with an infrared temp gun (very useful tool for many other jobs on a car - misfire, sticking brakes, etc)
Let us know how you get on with it
