I agree with Mike..
You should think about:
Full exhaust setup (Lts, Mid, Axel backs Flow masters arent the greatest)
Udps
Relocation Brackets
Lower control Arms
Panhard Bar
One peice drive shaft
and since you are doing Spray I would do some CMDV Delete plates.
I recommend the C&L Racer intake it rates just as good if not better then the JLT II and it looks nicer..
Basically what I am saying is get some N/A work done first.. You will notice a world of a difference with just a CAI intake exhaust and 93 oct tune...
