Advice:
Strip the sides, might have some nice art under the black paint.
Unhinge the control panel, spin it 180* , plug the old start buttons, drill new start buttons BAM! Joysticks to the left of the buttons.
Replace the power supply, they are ~$20 not worth ---smurfing--- something up over such a small amount.
If you arent comfortable fixing the monitor , either get a replacement chassis or send it out for repair. There are a bunch of guys over at KLOV that specialize in it.
I'd just order new sticks and buttons (they usually come with cherry style switches), I'd suggest TornadoTerry he sells Killer Instinct kits.
Front glass is an easy fix, go to home depot or lowes and have them cut you a piece of plexi, you can get some barrel locks for the coin door while youre there; and get an extension cord, cut the female end off and replace your power cord so you have a ground pin again
Also, I reported your post saying you wanted the thread moved, so hopefully it'll get moved over to project announcement.
