Remove the white wire that is running from the 5 way to the volume pot loose at the volume pot and move it to the center post on the tone pot
Not sure I would recommend removing anything else, it looks like he just needs to resolder the ground and the output jack, and then that one white wire needs to go somewhere?

Sounds good to me!

The black wire grounds the tremolo -attach it there
The yellow wire goes to the output jack - the center wire is the signal and the bare shield wire is the ground.
Yup.

Neither. The worst thing is you get silence. Or you could get a thin, out of phase sound... The voltage from pickups is measured in millivolts, not enough juice to damage you, the fuse, or any components in the guitar or amp.

I think you're probably just looking at worn out pots and a worn out switch.
My guess is that you could spray some contact cleaner in there and buy some more time, but at this point, that guitar is probably twice as old as those parts were intended to last...
Those potentiometers are called "alpha pots" and they are essentially the cheapest, lowest cost part you can get. Same thing with that "box" switch. They are intended to work for 2-5 years, which is usually plenty for a beginner guitar...
However, those Raptors are decent playing little guitars, much better than comparable Squiers, in my opinion.
Like the saying goes, "If it's worth doing, it's worth doing right."
Since you've already got the pickguard off and you've got a soldering iron, I think you could probably get a complete upgrade kit for around 20 pounds. See the Stratcaster Wiring Kit at the link below:

They've got wiring diagrams too.
Again, you could probably get away with just spraying the pots and switch with electronics contact cleaner, but if it's a guitar you plan to keep, I recommend that you upgrade the parts.
Hope this helps, good luck!
