Yea, it was interesting, especially since my gf at the time was in the car too. To get started, I needed to have the car in first gear, and then use the starter to drag the car along until the engine fired since pressing the clutch did nothing, and you could only engage or change gears when all the shafts were stopped or all the shafts were at similar speeds. Most of the time on the highway it wasn't too bad, since the 2nd and 5th gear synchros were toast anyway, so rev-matching was nothing new. Tolls were difficult though, I was praying the starter motor wouldn't quit or I wouldn't get stopped on an uphill incline.
Since things seized up and weren't dragging or sliding, I think the damage was pretty minimal. I changed the whole trans at that point to get better synchros too, and had no probs installing a new pilot bearing so I think the e-shaft was fine (the pilot bearing shell didn't appear to have spun within the e-shaft). If its just noisy, you should be OK still, maybe a little light scoring on the input shaft.
