Jpac / jamma + xbox a few questions

[Dutsk]

Hi guys,

So I've got my JAMMA cabinet running the video for my xbox and it looks decent, some slight flickering upon first powering on. However, I do NOT have sound and it seems my current stock control panel only has 3  out of 6  buttons cooperating (joystick not working). I have not programmed my jpac with button assignments because I'm not sure of what USB cord I would need.  My CP has a SKINS GOLF game 'flip' joystick seen here : http://www.quarterarcade.com/Game.aspx/10132

Questions I have:
Is this joystick compatible with xbox? Can I program it using into my jpac?

What's the easiest way to get sound working with my setup?

I've read threads where you need a sound card with an amplifier, is this what I need for an xbox / jamma cabinet..

How do I program my jpac?

I believe I need a video cord to USB of some sort to connect to my computer to use WINPAC..

Extra buttons?

For a new CP, I'll need more buttons. Do I connect player 1&2 first 3 buttons to jamma then the extra I need (3 each) to jpac?
