anyone found a prayer of some sort that would be considered a Last Rite that is spoken before someone dies, not the Oath to bring quick death to a Fallen Commrade, that doesnt really fit...it'd be for someone like on their deathbed spoken by a priest

The other one in the Imperial Infantryman's Uplifting Primer is the Death Incantation: I fear no evil, I fear no death, for the Emperor comes for me. Short sweet and to the point, it's definitely a warrior prayer. I imagine full last rites would expand on the theme: don't fear because the Emperor will protect your soul in the darkness, your lifetime of service shall be rewarded, you shall sit at the Emperor's right hand forevermore, etc.

I found a actual last rites as given by ayatani Zweel to Caffran in Dan Abnetts book " Armor of Contempt" ( Gaunts Ghosts series / Tanith First and Only )

"Is there anything you wish to confess at this hour"

"I hear and understand those sins as you have confessed them to me and i absolve you of them, as I absolve you of all other sins you cannot ennumerate. It is in my power to do this thing, for i am a ayatani of the Holy Creed. The winds have blown your sins away, and the Beati has blessed you and, though there is pain, it will end, as all pain ends, and you will ascend without the pain of the mortal world to the place the God-Emperor of Mankind has set aside for you at the train of the Golden Throne of Terra. These last rites i give you freely and in good faith"

That's awesome... Hadn't gotten that far in the series yet; so small spoiler. But awesome nonetheless.
