Don't be sorry thats what this whole thread is about! As far as blowing up your empeg, just make sure the resistor array checks out with a mutimeter and the display itself plugs in correctly (pin alignment), as far as the knob board just test it before you connect it to the empeg...

As far as the parts you've come up with, they look good to me, but I'm no expert on things of that matter, perhaps Mark or someone with a little more expertise could look those over and give it a blessing?
