This mod will raise your truck ~3/4", in my experience.

Correct.

It subtracts 3" of the drop your pinion 'sees'. So, in your case it would be like a 3" coil drop worth of pinion angle change. I doubt you would need shims, but each truck is different.

Holes #2 and #3 in the bracket would then need to be re-drilled into the cross member because there were no holes there originally. The original cross member holes can be re-drilled and matched for 8 total bolts? Am I seeing this correctly?

Yes, but I only re-drilled the two closest to the pivot point, and used six 7/16" bolts per side for 12 total. I've also seen guys do 8 per side.

Did I read LS2?!
