Congratulations on your purchase. I also have a Contemporary and Nick Acton has done a lot of great upgrades for me: quick jacks, roll bar, seat belt anchors, aluminum gas tank, correct dash, dropped pedal box, aluminum fender liners and the list goes on...
As far as shows, even though they are not in PA, if you can make either of these, you will see a lot of Cobras:
