Problem solved. I went and got a 12212156 operating system from an 02 Express Van off HP Tuners (that OS allows removing the PRNDL - thus saving the wire splicing) - and the one I found from Hutchinson had a 1996 Vortec 5.7 tune with it. I went into the tune and double checked the PRNDL and VATs, uploaded it into my 0411 (costing another 2 credits - 4 total for this project), and now it started right up and seems to run and drive fine - no CEL after a longer trip around the block.
In uploading the 12212156 Vortec 5.7 Tune I noticed that it warned me about OS - tune being different (I can't remember the exact language), and that tipped me off to the fact that I needed to upload everything to the 0411 (OS and everything). I guess that is risky in that you can "brick" the 0411, but I did not have any issue with that.
Hindsight being 20-20, I didn't really understand the interaction between the 0411 hardware - the operating system ("OS") - and the tune. While I looked at the OS on the 0411 I had (2001 4.3 V6 I believe) and wondered how that was going to work with my V8 (being from a V6 vehicle), I didn't really understand it totally, I just took it on faith that it would work. I think I somehow further confused myself by thinking that I was able to upload a 1998 5.7 Vortec tune onto my 0411 (there are multiple stock tunes available on HP Tuner) without using credits (I think what I actually did was download off my 0411 the existing tune, and then make some changes) . . . but clearly I must have never done that, and just mis-remembered doing that. Remarkably, when I compared the 4.3 tune to the 5.7 vortec tune in HPTuners VCM editor there weren't a lot of differences that would make much of a difference . . . so most of my issues must have been coming from the Operating System being wrong (which, as I understand it, runs "behind the scenes"). Remarkably, the truck ran with the 4.3 OS and tune, though terribly.
Now I understand why people go hunting for certain 0411s (which I didn't do) . . . that alleviates the 4 credit situation if you can find one with an OS that will work with the truck and then just modify the existing tune that works with that OS.
Regardless, truck is now ready for new engine with minor modifications, and I learned a lot.
