I wouldn't bother with most of the things you're considering honestly. That engine should run fine on the stock black box PCM, stock throttle body, and stock MAF. Changing MAFs may actually make tuning more difficult. The 0411 PCM swap is mainly beneficial to those interested in doing their own tuning IMO. The VMAX plenum spacer might gain you some power.
FYI you'll probably get more responses if you copy/paste this post into a new thread.
Thanks for the advice on everything. I do tend to ramble in my messages, I will try to nip it in the bud next time. Also I appreciate your response and honesty. I kinda figured that everything else was not really going to help but I wanted reassurance from someone else who actually knows a bit more about this stuff than I do. Looks like it's now time to see how long it takes my engine to blow and then start installing the new one and take it to get it tuned and broke in properly.
