I'd like to redo my guitars electronics, because

1 - I have a suspiscion all the parts suck
2 - the neck p-up keeps crapping out (either the volume or the switch).

Where can I find
2 volume,
a tone,
and a new toggle switch?
And while I'm at it I would like to install a coil tap, if it isn't too hardso what would I need for that?

And how would I wire these? Diagram/photos?
I am in the UK BTW.
