You need to combine the wind pressure coefficients when loads are calculated. However, you can not always combine the wind pressure coefficient obtained for windward and lever sides. For example, when you are calculating wind pressure in a building, we have to consider the internal pressure...

If there is a considerable shear force, we need to provide a shear key. We can not avoid that. If the shear key is provided directly bellow the wall, there will not be much affection on over turning. When we move the shear key toward the land side, factor of safety for shear increases...
As I think this could be due to the elastic shortening of columns. Axial load of columns increases with towards bottom of the structure. When axial load is high, there may be higher elastic shortening. Then support moment will reduce. When we go up, axial force decreases and shortening reduce...
As far as I know, you can not model a beam as T-beam in etabs

Please refer following links to get the knowledge about anchorage and blond stresses.
Simplified methods of obtaining the anchorage length and method of manual calculating with example can be seen through following links...
When there are cantilevers in both sides, fists you have to find the worst case. This is actually depends on the axial load and the bending moments.
you can consider three cases.
01 one side loaded
02 other side loaded
03 both side loaded
each case find the bending moment and axial force...
