Lets be realistic - at some airports (esp in HK/China) a TA is not unusual. Let me clarify your report that you quoted:
1&2: work together as a team to understand what is going on
3: listen to the radio
4: Do not ask ATC about traffic unless you are confident an RA is imminent (beware aircraft levelling off 1000ft below/above)
5: Do not adjust heading due to TCAS (but you can, and should, adjust vertical speed or IAS)
6: Appears to be a VFR rule. In IFR you respond to TCAS RAs (not ATC) accordingly. ONLY if you are following an RA AND your are still on a collision course should you adjust heading.
