Update for AScheele and others: Today I took the time to swap things around on the Injector Pressure Regulator, and I also tore apart and cleaned the fuel regulator mounted on the side of the filter housing, and pushed compressed air through the return line.
I am unsure which of these did the most help, or if it was a combined effort, but the truck now starts pretty good (got to crank just a little more than I like, but not to the point that it is what I would call it hard starting). When you get into the accelerator and let off it don't stall either.. Double bonus!
We went for a 7 mile joyride in the old girl, and the oil level is right where it was previously, so i think the fuel in oil problem is solved, but I do believe I in fact have a bad injector, as at an idle it has what can best be described as a "miss", so I guess the injectors will get pulled again and sent to be tested.

Im glad its starting better for you. but before you jump into getting injectors removed and tested, make sure all the wiring harnesses under the valve covers are good. i had to replace all of mine, and two of the connectors on the main wiring harness when i first got it.
