I think FTN and SCT arent really necessary.
Maybe only SCT if you have really good speed.

FTN would be useful (because of pre times) for this ppl who sells what they download, but i think this ppl prefer the axx FTPs...

Im sure you can find the content of FTN packs on other sites...

As ppl said, you just need to add HDbits to your sites and you will have every thing you need.
