In looking at the two site you mentioned above, these are more than I thought a "tuner" is. Is this best to be farmed out or something that I should have with my engine conversion? I was thinking the tuners as the devices you buy to add enhancements to your ECM like what Diesel guys have from Bully Dog.

those are programmers, EFI Live and HP Tuners are tuning devices. There are BIG differences between programmers and tuners.
Look to Nelson Performance for a tune. Nelson Performance - Performance without Sacrificing Drivability
Update. I bought a new o2 and the HPTuner software. (It hasn't arrived yet). I also disconnected my Oil Pressure Guage that was connected to the sensor on the back of the 5.3. How does this look?
And this one.
