I put AP coilovers on my 4mo and the ride wasn't too bad at all. Was really good actually. Or Weitec make a good kit too.
Failing that, you could just go straight to the OEM R32 suspension? It is meant to be a reasonable set-up. As you say though, matching the H&R OEM with the Eibach springs would be good too.
Personally I would run the Weitec coils though. You don't need to make them that low, the ride will be not much worse than original, but a lot sharper, and will cost the same or less than other options you are mentioning.
