Check my build thread. I had (still own) the pink springs on my Foz, so there are some pics on there of the ride height. It still got saggy-butt, but Subtle Solutions sells 1” spacers. Pushed hard, the car still wheel-barrowed with the pink springs, so I ultimately went with coilovers. No, they’re not for sale!
The pitching you’re talking about! You can reduce some of that with an alloy pitching control rod, and body bracing underneath ... but yes, lower and stiffer springs will help alleviate most of that, as well.
Lots of groovy stuff can be done to these cars, so have fun with it ... and hopefully you have deep pockets or fortunate finds!?
