When they installed your headers, they might have stuffed up your O2 sensor (broke a wire or similar). You need to get your car checked out. Something is badly wrong. I have driven at full throttle 4000-7000 rpm in a day for 90 minutes and that only consumed 30L/100km.

No it shouldn't,just make sure U turn it off before pulling the fuse/battery lead cause she will go off!

It depends on the alarm system that you have. For the stock Euro's alarm system, there is no effect.
