1) moved back 1" on the trailing arm to align with the upper hole in the frame.
or
2) left in the stock placement on the arm,... and the frame would have to have the spring cup hole (in the frame) drilled 1" farther forward.
Does anyone see issues with either option?

This crossed my mind as well. So then I thought, "Well, it must just be from the suspension drop, and the lower spring mounts are actually back from where they should be like the axle, so shortening the arms should fix it."
But I'm starting to gather that the axle position is off at stock height too?
I tend to say move the spring mount back on the arm. Although, that will make the spring act stiffer (just a little) and may raise the rear height a little. It would also cause the springs to be a little wider at the bottom mount, but you could modify for that while you're at it.
If you move it forward on the frame, you'll have more weight behind the spring, so it will squat the rear and pick up the front slightly. It should keep you over the top of the trailing arm better though (side to side).
I think my vote is for moving the mount on the trailing arm back toward the axle.
