If the front end rides higher, then replace the rear springs when you do the rear end, but if the car's still level, then just replace the rear shocks.
A few summers ago I had a 2000 Golf that I put new struts and rebuilt the front suspension. I put that entire suspension on a 2003 Jetta a year later but replaced the springs with low mileage used neuspeed sport springs that I got off of kijiji. The springs made more of a difference in the way the car felt more than any of the other stuff, and the springs were like 1/3 the cost of the other components (bilstein touring stuts and an IDparts front end kit). I know that I replaced worn sport springs with new, stiffer sport springs but the car did not crash over bumps and actually absorbed some of the impacts. The car had about 195k km on it on completely stock suspension down to the tie rod ends IIRC.
I've seen people say that springs never need to be replaced, but they made my car feel brand new. I know factory springs are expensive, but you can always get good quality aftermarket springs for cheaper. I am not sure that you could get a stiffer spring in a stock ride height though.
