i've just about finished doing the same thing - emblems, fog bezels, grille rings, etc.
You can find it all on ebay, but the price adds up.
Tail light options:
If this is an OEM set, it's a steal
Aftermarket tail lights
Tail light bezels only
Grand Cherokee badges
Jeep badges (front & back)
Fog light bezels
Grille Rings (Mopar)
Grille Rings (Safaripal knockoffs)
- I opted for these. Some of the rings might be a mm off on fitment, but I've monkeyed with my grille so much I'm not sure if it's the rings or grille. Either way they fit great. Also, they did have some small scuffs which could be polished out, but unless your 2ft away you'll never see them.
Get one of these
for removing the tape after pulling the badges.
I didn't get the step pad trim or front lower applique in gloss, so I don't have those part #'s. I opted for the textured black pieces similar to the rest of the lower body trim.
Do you have color matched door handles and mirror caps already?
I'm just waiting for the tail lights to get here so I can swap out the lights and Jeep badge on the lift gate.
