Those are really overload springs. Unless you're towing stuff or bouncing through the desert in a baja bug, they're probably not what you really want. Adding an air shock on top of that is most likely going to give you a bone jarring ride as your spring rates will likely be too high for the weight of your car.
The correct way to raise the rear ride height is to reindex the rear torsion bars. You can use the charts in the topics below to find out how many splines you need to change on the inside and on the outside of each bar to change the ride height from its current position. (Resetting to stock height requires knowing the stock spring plate angle for your year of chassis.) For example, to raise the car 2 inches, you'd rotate the spring plates down 10 inner splines and rotate them up 10 outer splines to give you a 5.5 cm raise (2.16 in).

edit: This assumes you still have rear torsion bars. If they've been removed, those overload springs are too weak to be used as a primary spring. You'd have to upgrade to proper coil-over shocks with the correct spring rates and reinforce the shock mounting points to handle the extra stress.
