Gobax said this after reviving Haahqae, so he would have heard that, yeah.
And yeah, just reporting the location of the cult lair to the temple would be sufficient for completing the job. They could send in the army to wipe it out, but as you point out, they'll likely confiscate any goodies inside and there's no guarantee they won't kill Tulbas along with the cultists (especially since he is pretending to be one of them now).
On the other hand, the only way Gregeddin and Haahqae can finish this job themselves is to wait for tomorrow then ask the temple for healing. And waiting could be deadly for Tulbas and who knows what the clerics of Takhisis will ask in return for their help?
