Those are second generation levers for which parts are still available.
You want to keep right G-springs and G-spring carriers on hand. The G-springs are wear items that are convenient to have around; and G-spring carriers seem to make it through a couple pairs of springs before failing due to fatigue.
I'd also keep right front lever return and thumb lever return springs because you don't want to be scavenging for NOS parts if you break yours after Campagnolo discontinues them (I bought the last two first generation right front lever return springs from Loose Screws).
Left G-springs and G-spring carrier might be a good idea but my left shifter still feels like new after 15 years.
