To do a sport rep or a retro mk1 look?

Agreed. Keep as is.

Definately keep the car as it is, if it will handle without going to low, it would also help keep the "oh it's a 1.0 Nova" look.
As for wheels, personally if you are going for 2.0 brakes, 15" astra steelies will cover these, are wider than 13" Nova wheels but give a similar look. Astra GTE14" alloys will also clear, I don't know if Nova 3 spoke alloys will or not, never tried. Again all these wheels will give an early 80's look.
