First off, welcome to the forums! I think you'll find this place a veritably knowledgeable consortium with a little personality spice thrown in for good measure. Plenty of information in the Accessories and Tech sections if you care to browse them.
As to your question, the best way to answer is - what is your definition of nasty? If you're looking to improve horsepower, you're on the right track I think. Aftermarket exhaust, Power Commander, aftermarket, lighter wheels - these are probably the quickest ways to see improvement in your new investment. If you need more, you're probably going to be looking at turbo kits. I suppose it depends on whether you plan on track time or not as to what upgrades would work best for you. If she's going to be a commuter, I wouldn't recommend a turbo kit as you'll likely reduce engine life exponentially.
