The weak part that i see is the 1.76 gear set unless it is a good aftermarket one sounds like you got a pretty good set up there .
Tod is right it is a hard hit on the drive line you will need good u-joints and drive shaft for it to really last i have ran stock gear sets for a couple of seasons before they broke but a stock gear set want handle a lot of hard launches .
One good thing for you is your car is light and that will help a ton.
