Hey welcome to the family and post pics in the members gallery of the new car.
I'd personally say get a exhaust first. From there look at engine management. Also look at springs, your stock suspension is pretty damn good but if it's not enough for you. Look at sway bars and strut braces.
I'd skip on intakes because your stock intake is pretty damn good if you really take a look at it.
Also I highly recommend looking in your area of the state boards and look for meets in your area, this is a great way to meet the subbys around you and get real time answers to your questions, without being bashed on nasioc for not searching. You can also see what others have done to their cars to get a idea of what you want. Like if theres a exhaust you like but not sure how it sounds, or if you want a idea of which springs sit the way you'd like your car to sit.
