It can be seen that the -306.15570 column represents the change in energy in the transition state calculation, so what do the other columns mean? Does the first column correspond to the intrinsic reaction coordinate?

I believe these are simply distances between the nodes on the string (possibly in mass-weighted coordinates). It is not a IRC in the rigorous sense. (JOBTYPE=RPATH searches for the proper IRC.)
