From what I've read, people report no difference in the ride between the spring and the hydropneumatic. I've never seen a car with a swing axle that hasn't had the hydropneumatic eventually replaced with a spring.
With regard to the brake cylinders, they are very expensive purchased new (around $180 each). The good news is that rebuild kits can reportedly be purchased at a regular parts store. The bores are standard sized and are the same as some older American cars. I believe there are two bore sizes. Have your mechanic measure the bore and head on down to the parts store. Ebay often has rebuild kits for sale, as well.
The shoes are extremely hard to find new, and I expect ridiculously expensive. Most folks send them out to be relined.
EDIT: I was reading the Heckflosse site and apparently the hydro cylinder was an option on the fintails.
