BD, nice thread!
I'd like to add one more point, which goes deeper into the "What do you do with your car?" question.
Try to learn about WHY you should, or shouldn't, use a given aftermarket component on your car. Reading the FAQs helps immensely. There are also great books on driving and suspension setup and you should read them.
What specifically are you trying to accomplish?
For example, I've seen many threads started by folks that want recommendations for aftermarket brake pads when they never exceed the capacity of their OEM pads. Why waste your money paying for upgraded pads when you don't need them? No one can see them. If you got 30k miles on your OEM pads, believe me, you aren't overtaxing them.
Understanding why and when you should upgrade your pads is far more important than what's the best pad. And the learning experience will benefit you more than all the opinions about which pad is 'best'.
Learn about the tradeoffs associated with the component. Harsher ride, more noise, more dust, shorter life, increased maintenance, warranty issues, more oversteer, more understeer, more bumpsteer.
You shouldn't put a stiffer rear anti-sway bar on unless you understand what lift-throttle oversteer is, when it will happen and how to counteract it.
Educate yourself on the 'whys'.
