Proper Mods

I'd definetely skip the TB and chip for right now. The Zex systems are meant to work on a stock car and definitely on a stock computer. I don't think you need to upgrade the throttle body either, the stock one is more than adequate unless you're making a substanial upgrade in horsepower. Its not a bad mod, but its expensive and in my opinion not something you need yet.

As for the other supporting stuff. I would recommend the MAF, I noticed a hug bang for the buck when I did mine. I'd go with either a C&L 76mm or a Pro-M 77mm. I have a C&L and am very happy with it. Get a Walbro 255lph fuel pump, they work great and are inexpensive. As for FPR, I have an Aeromotive that I haven't installed yet, but from what I'm hearing Kirban seems to be the consensus brand around here. I think you should be OK with the stock injectors for now, but if you want to upgrade you definetely shouldn't need anymore than 24#'s. If you upgrade injectors be sure to get an MAF calibrated for 24#'s instead of the stock 19#'s. Hope this helps some.
