Thanks for the information Jake. I've followed your advice and have run the car from cold to operating temperaure several times now. It has gone from stumbling and stalling to confident smooth running. the Idle has settled to a rock steady 800 rpm, and there was an intermittant miss, perhaps a sticky fuel injector, that seems completely resolved. The engine now idles confidently, runs smoothly, and revs freely. It's insured and gets plates tomorrow.
