No such "combined" .tpr file is necessary; it wouldn't make any sense.  What's 
in a .tpr?  Initial coordinates and simulation parameters - would it make sense 
to concatenate such information?

Use the .tpr file that you used to run the initial MD as input into ngmx.  The 
.tpr is simply used to read in the initial coordinates and allow for the display 
of a subset of atoms (much like all Gromacs tools).
