My immediate problem is with every throttle advancement on takeoff, I get the Vibration warning followed by the retardation of the throttles. The only override is to hold the F4 key down until a safe altitude is reached. Usually everything operates as advertised from there.

I don't now why this is happening to you, because I just did some takeoff testing with the L-1011 II in P3Dv4 and P3Dv5 using my Logitech Extreme 3D Pro joystick, and I didn't get any vibration allerts during takeoff (I was using the throttles at 100% for the takeoffs).
