Any decent online vendors?

I'm looking for some reputable online vendors, and thought I'd check with you guys to see if there's anyone in particular that you all like. My car is totally stock, so some of the things I am looking to do are drop the ride height, put in a shorter-throw shifter, probably replace some of the exhaust components (i.e. header), and any other engine/suspension mods that might tickle my fancy. Basically, I want to build somewhat of a sleeper that I can also auto-x on occasion. Unfortunately, I am TOTALLY unfamiliar with Hondas. I am actually more of a Ford guy, so these engine designations I've seen around here are really foreign to me. If anyone can help point me in the right direction, then, with vendors and how-to's, I'd greatly appreciate it. Thanks.
