Opinions are like you-know-whats, and here's mine:
Get the exhaust before you get the intake. The sound improvement is more pleasurable, and I think the performance gain might be a bit better than just an intake.
Shocks are a good upgrade, but I would get some FM or Racing Beat sway bars first. That and a good alignment will do wonders for your car.
Bum as many rides as you can with modified cars to see what suits you best...
Good luck!
