So I bought a chimera today. The box came with an extra 2 sets of ship cards and card board set for hull zones and what not. Did I hit the jackpot?

No, those are included. The extra ship cards and cardboards are so that you can turn the original ISD expansions into Kuats and Cymoons.

yup that's standard, some people have 2 normal ISD and can, with getting a chimera, refit them.
