Stalls at temperature, only when coming to a stop.

So, in general, not bad news, as I read it.

You clearly have vacuum leaks to clean up. Getting the injectors out, IIRC, is a bear of a job, so I would revisit that thought later. How did the determination that it is running very rich come about?

Your belief that checking the camshaft deviations should be done with the engine at temperature is correct. Discuss that with the shop to see exactly what they did. Typically that is caused by worn actuator pads - replacing those is DIY-able, but is around 4.5 wrenches out of 5 on the difficulty scale.
