Picked up another rectangular tube

[lnx64]

Hey, quick question. Due to me having some hearing issues, and closed caption not always being the best solution, I would like to add a headphone jack to the side of this TV. I used to have an old 19" rotary when I was a little kid that had one on the right side. I would like to add one to this TV, and I could easily make a perfect clean round hole for such a jack. That's not a problem.

The problem though, is how the heck do I wire it to this speaker? It's an 8 ohms speaker. I can easily probably use one of those mono ear buds. How can I wire in such a headphone jack?

EDIT: Also, upon removing the old flyback, how the hell do you remove the focus wire out of the CRT socket?!
