Hmmm, not sure I can help there. I do have the under dash loom if you need it, but not the dash to engine bay.
Replacing the dash is fun [xx(]. All I can say is, make sure you have a copy of the Ford workshop manual on hand (they pop up on eBay from time to time - 4 Volume set). You need to pull EVERYTHING out to replace the pad. You may as well repaint the dash accessories while you're at it. They've gotta come out anyway. If you're planning on fitting extra guages etc., do it at the same time. Makes life a lot easier.
Depending on how much you want to spend, these don't look too bad as a budget coil over:

Wheels, well, thankfully there are plenty of fwd cars with 4x100pcd. My 16s came off a Civic. See if you can find a set of light weight 15s.
