Best you can do is find a local company that has a 'guy' that can choose a valving based purely on experience. Though I have serious doubts about that working in practice (from my discussions and experiences in damper-walhalla Holland).
The other option is finding something close to your needs with a wide adjustment window and working adjuster (adjuster works in the right direction, all adjusters work the same way, every click covers a similar part of the range). In practice only decent shocks fullfil the first criterion (koni and similar) and only the very best shocks (Ohlins, Penske, Bilstein ASN, etc) will fullfill the second and third requirements.
That's why I wouldn't change the rear setup. For the stock setup there is known to work valving you can build on. For custom stuff you're on your own. Particularly for a car that has seen little use for timed events (S13).
By the way, driving on the good stuff is like magic. Patches of asfalt that used to get the car out of shape leave it undisturbed with great shocks. You shave 2secs of your pace while driving at what feels like 80% of the previous effort. Its relaxing 
My best bet at an of the shelf setup would be:
Keep the live axle, don't add a turbo, order N2 spec ennepetal 36mm Bilstein coilovers front and rear. Enjoy
Yeah I will look for a local expert.
I have never seen the Bilstein N2 coilovers? I did a search and couldnt find them, have you got a link?
