(2) Are you talking front coils, rear leafs, or both?
AFAIK nobody offers lowering coils for the front.
I don't know whether anyone offers off-the-shelf lower rear leafs. You may need to look into getting your rear leafs de-arched by a spring shop or consider going with an S-Dad Mod (6-lug leaf swap).
