The newer Ac Delco 60G or Bosch Duraterm are self limiting and won't swell so they are okay with longer glow time. So I would replace them either way but be prepared that some may be swelled and will be a pain to remove. Double check the wiring they did for the glowplug system, it may have some issues.

Since you said it's smoking while cranking, that means it's getting fuel so it does sound like a glowplug problem more than likely. I would however make sure the fuel system is 100% tight from tanks to engine, air intrusion is the biggest thing that can cause all sorts of issues with starting and running. Also these need to crank fast to start well.
