Re the pedals: if you swap in the modded VW set you'll probably have to move your clutch master cylinder closer to the brake MC.
The stock VW pedals use a cable for the clutch engagement. Your appears to be by hydraulics. I'd just put nice billet petal pads on the existing setup.
On the dash. I greatly prefer the existing one with the glove box. It makes it look less kit car-ish.
