Good points Rananim. The one issue I see here is with your more complex airspeed unreliable scenario with STS trim involvement is that you need to recognise that there is a linkage between the two, and then do the "Runaway Stabilizer Trim" memory items in addition (should have already covered the initial items in the Airspeed Unreliable initial memory items, Autopilot Off, Autothrottle Off),then Stab Trim Cutout switches (both) cutout, and you are back to a "plain vanilla" (not to diminish the degree of difficulty) airspeed unreliable.
Similar to the windshear escape, it helps to "blip" the trim every couple of seconds so you aren't wrestling the trim during the escape.
