I don't know of any aftermarket headlights that are quite what you're looking for.
I remember seeing a set that someone had taken apart and painted the "shiny" part behind the reflectors with black paint. then put them back together. They looked pretty good.
As for the tail lights, look around a bit. Several people have used "nightshades" paint to tint their tails darker.
Seems to be a simple project.
As for Body Mods... well there really isn't much out there that I would recommend. There are a few different bumper kits and some side skirts, they look kinda dumb IMHO.
Just a note of caution, check your State's laws concerning tail lights and headlights before you go tinting anything. Especially if you ever plan to sell the car to someone else. I know that in Maryland you cannot sell a car that has had its taillights tinted without a whole lot of trouble for the new owner.
If nobody answers your questions quickly remember to use the search forms at the top of the page, there is a lot of good information there if you're willing to take the time to look through it.
