Stating the obvious now but I just really got started on this this morning.
Man it is SO easy to say "Oh yeah, just plot a few points you are sure of, overlay the constellations until one fits, then work backwards to find the others." In practice, it's really difficult to do, especially given how few confirmed specifics we have. I might as well have said "Oh you want to climb Everest? Simple, just keep going up."
Those of you who have gotten as far as you have, I salute you.
