Yeah, you can leave your stock values in there. I haven't looked at a stock tune for a while, but if I remember correctly, the stock values are set a little lean.

Probably best to leave it at 14.7 for idle and part-throttle.
Some folks are running a bit leaner, but tuning for that is more involved.
The pcm expects it to run at 14.7, o2 sensor switching is set around that, ltrims, etc.
WOT, could be anywhere from 12.2 to 12.8. Will you be tuning with a dyno?
My stock power enrichment was set rich from the factory. EQ ratio of 1.25 from 2400 rpms and up, which is 11.7:1 based on the 14.63 stoich afr setting in the tune.
