Justin,
Only problem is I need to change this parameter
energygrps
to track the energy on specific groups in the simulation. Is there a
way to modify the simulation parameters to track these energies?
Modify the .mdp file the way you need to, create a full-system .tpr file, then
run it through tpbconv.

If you have a .tpr file, then the .mdp file is a step backwards. You don't
need it.
Assuming you want to do some sort of re-run procedure, you simply have to
run:
mdrun -s subset.tpr -rerun original.xtc
(where original.xtc is your trajectory file that contains the same subset of
atoms as subset.tpr)

3nd. by creating a tpx file for a subset of your original tpx file,
which is useful when you want to remove the solvent from your tpx
file, or when you want to make e.g. a pure Ca tpx file. WARNING: this
tpx file is not fully functional.
