Lift kit + suspension adjustments

Im looking at lifting my mk3 scout 40mm with an ebay kit, but ive found some info that i wanted to clarify here:

• Apparently a lift kit warrants stiffer shocks - what can i buy that will bolt in?

• Mk3 octavias dont have camber adjustment apparently - do i need different camber/toe/caster? specs vs stock, and what can i do to get caster adjustments for the car? id rather stick with VAG parts if i can, and buy 2nd hand bits that are in relatively good condition

• and while im at it, i want to buy a vcds cable + laptop, but what im seeing on ebay is only for pre 2017 models - are they legit or knock offs?
