you can go to town, get a scroll and come back to ressurect.
if the PC burnt in lava the resurrect scroll will bring them to life but they will instantly die because they are still on lava
you can teleport the ashes to another spot (i haven't tried this, but others are adamant you can do this)
If you leave anything on the ground anywhere it will be there forever. e.g. you wanna steal a house and leave stuff lying around, go for it. same as dead bodies, they'll just stay there.
I hope someone adds a mod to allow you to drag bodies... this would be awesome for stealth killing and for dragging pc dead bodies out of danger.
