I figured that part of the reason that the new sensors didn't take was because our generic TPMS didn't have the capability to communicate the Crossfire. I'm inclined to go with @Deepsea21 's direction here, personally I've never seen the value in the system. None of my other vehicles have it, either. Someone else pointed me to this thread, which details moving the pin for the light itself to an unused spot on the connector. The car has passed inspection with the light on though, so I'm not too worried about that. It would just be nice to not have the light on all the time.

The Launch CP123 scan tool has been confirmed to clear SRS faults in another thread in this forum, so I have one of those on order now. Should see it next week sometime. Fingers crossed that it gets rid of the airbag light.

I had seen some recommendations about doing cam and crank sensors preventatively, but hadn't gotten to it yet. I like the idea of just having them on hand to replace when they start to go bad. Good to know about the other little things to do to save money in the long run. Thankfully I haven't had any sticky key issues, but I haven't checked the fuse panel like you recommended.
