if your going to go full coilover then I'd recommend the Tein SS, Tein Basics, or Apexi full coilovers. the auto-x guys seem to like the Apexi more then the Tein, its a stiffer ride.
as for shock/spring combos, some of the best combos are the Eibach pro-kit, Neuspeed, H&R for springs. for shocks Koni yellows are the best you can get.
