Is it a V8 or V6? I wouldn't bother too much with vortex generators (or do a search here for discussions on them). The air dam up front, and tire spats are a great place to start. For lowering, it likely will help, but if you're aiming just to save money, it probably won't be worth it, because the cost will take way too long to pay for itself in savings. However if you want to do it for looks or anything else, then it's all up to you.
Do you do a lot of city or highway driving? I would also recommend an ultragauge or scanguage, to get real time feedback of fuel economy.
