I would only recommend the cam gears if you had cams. New spark plug wires won't do anything unless you need new ones, and in that case, OEM are the best.

Listen to this!

nope
save your money for cams, go ahead with the basic bolts IM TB header exhaust, then if you truly want real horsepower look into turbo or block and head work.
