I'm more concerned about the other bolts. One bolt fell out, are the others loose?

Any signs that the flywheel has been loose?

Your into it this far, I'd inspect the other bolts, crank flange, and flywheel. If there is any sign of the flywheel wobbling, I'd put it back together and park it, till you have time and funds.
