Some pretty smart guys offered suggestions on the very same issue a few years ago. I'd give exactly the same advice today. If you desire legitimate performance level shocks then get them, and let the Airlift bladders do the rest.
Search member 95 Wagon and you'll find a treat on modding your (amazingly still) functioning compressor to operate with the Airlifts.
Regarding springs, on a Cady the autoleveler was designed to bring the rear up the last 1 1/2" to keep the car at correct ht.
