It's real easy to get caught up in the "need for speed" and have your head spinning with all the different ideas of what you want to change on your car... *but*, you'll probably find that you'll shave more off your run times by improving your driving than continually spending money on the car in the quest for more speed. Plus, it's a hell of a lot cheaper!  Just the new coil-overs you did recently will probably make it a changed car out on the auto-x course, and you'll need some time to get used to that, explore the car's new limits and feel out the new handling balance.
Just some friendly advice and my opinion of course...

Like they say: "Fix the nut behind the wheel first"...
Another thing to consider, what's your primary intent for the car? For me, I'm all about autocross (and soon rallycross hopefully!!) That's why I'm staying with the stock turbo/intercooler. A bigger turbo will make a ton more power, but the lag will make me slower on most autocross courses. However, for drag racing, that big-ass turbo is a huge asset. What you decide to do on the car should be determined by your goal. Of course, just building a monster of a WRX is a respectable goal in its own right, but it will usually mean that you'll compromise your 1/4 mile times, or your autocross times, or both.
If you decide to focus on autocross, remember that the WRX already has a pretty good power and traction advantage over the rest of STX. Handling should be the focus. Those coilovers are a great start. New rims/tires will help even more. That sorta stuff will be far more useful than making more power.
But as was mentioned, seat-time is the #1 thing that will make you faster. Look at Debbie... her car's stock w/ R-compound tires, and she MOPS the floor with all of us! God help us if she decides to move up to STX, I'll just go back and hide in NSM.
