Since you're 75mm intake and t.b. I'd suggest you get a 3/3.5" MAF housing ready for when you see a tuner. He'll be able to tell you the % cycle of your stock injectors, if they're over 90% (most likely) you'll have to switch to something bigger. Bosch and Denso should be plug n play.
Also cams would be great but do you know what you're setting yourself up for? It's an 8 hr job at least and you have to get new valve springs and shims to clear the higher cam lift.
Maybe you should look into a 3.9 or 4.08 final drive gears. That will wake the car up for sure and you won't need to open the engine. There's plenty threads on this forum.

This stuff^
Bigger injectors doesn't mean more power. Bigger injectors are to keep up the proper mixture when mass amounts of extra air is added into the mix.
The fact you have N/A bolt ons, I highly doubt you are going to need anything over stock. The only reason FI guys get it is because your literally adding a leaf blower/turbine to force air into the engine. Seriously screwing up the mixture.
Run new stock injectors.. or like above have your show test the exact ratio and flow of them to tell you exactlt what your application requires. But if you want you CAN buy bigger injectors. Just cost you more money for no reason.
