For stock ride height, the GR-2 strut is awesome. My buddy runs them in his lowered neon (about 1.5-2" drop on it) and it rides like stock. If you want to lower, get the Illuminas from Tokico. If you want to be able to play with the dampening without lowering (or only on a mild drop), the KYB AGX is a really good shock for that, I've found.

As for springs, junk yards have em probably cheap. Sometimes you can score some in good shape (Avengers/Sebrings I believe run the same suspension setups). If you really need them, I still have my stock springs, and they're no longer any use to me, so we could work out something for them if you'd like.
