In all honesty, that's great you want to fully invest yourself on the car. Really, good for you. If you have the money, do it. But on the same token, I would start slow. Take your time to read the FI section on the forums.

As someone told me here, suddenly adding power/handling mods will only mask your mistakes on the track or road. So get familiar with the vehicle, start with basic mods for these platforms. Headers, E85, Tune, Tires. Going FI is no joke and even those who are at that level have encountered several issues or some unlucky ones have heard their engines play a rendition of "Knocking on Heavens Doors".

I was just like you when I first got my vehicle, but I took all the enthusiasm and used it to read and learn about the pros and cons about every single mod, no matter how big or small. So really, take it slow.

All of your questions are valid, but if you have to ask, you're probably not ready to go full bananas on your build. I mean this in the nicest way possible. I would hate to see a future post on your behalf on how your build went horribly wrong and now your dream car is just sitting on blocks.
