I'm confused on how to wire the output jack.

1. Is the hot/outside tip the longer of the 3 tips on the end of jack?
2. For the inside/earth contact does it matter which of the 2 'short' tips you solder to?
3. In the diagram, my blue arrow is pointing to a wire that doesn't exist in my set of electronics. I think I have an extra wire (yellow) that is already attached to the tone pot, so can I just remove that and use it for this blue-arrow wire?
