SlvrS197,
Definitely put a drive-shaft on your list if you're looking at drag racing with slicks or drag radials. The factory drive-shaft will not last too long, even with a bone stock car on slicks! One piece drive-shafts are the way to go though for any drag racer. Your clutch should last a little while, it really depends on how much you hit the track with slicks.
Nitrous- don't worry, you didn't waste your money buying Bama tunes! Bama can tune up to a 100shot of nitrous for any '88+ Mustang. If you're looking to put spray on your car, give Bama a call and they'll hook you up with a nitrous tune asap!
Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 10AM-3PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!
If you have any questions, feel free to contact me too.
