No worries on the transmission, as long as no oil ran out of it.

I'd forgotten the order of assembly, as for the bolt and u-joint. The trans and the diff don't care at all about the driveshaft except for it being properly installed. What is important is that the u-joints for each half of the driveshaft are lined up, on the spline. If you have a vibration when you get it back together, the worst case is that you would have to rotate the rear section half a turn, if the u-joints are properly installed. I've boogered some myself, back in the dim and misty past. Once you get it back together, share a picture with us. That would be the easiest way to verify it. You could look at your previous picture for reference, as well. Perhaps there are some distinguishing features that will help you.
