Power adders are the way to go with the 4.6L engine. I would go with an ATI Procharger, I really like that you don't have to put a hole in your oil pan (..cringe..). That is on the pricey side of course.
Gears are a must! expect $400 to $500 for those.
Exhaust system:
Headers - $200-$300 + install
H-pipe - Anywhere from $150 to $375 + install (depending on whether or not you have Cats)
Cat back -~$300+ and then add installation.
Pulleys will set you back $80+
K&N - ~$50
That's just a start.
